Above build warning comes when CONFIG_HOTPLUG=n because argument of
free_dynids() in serial/bus.c is a struct usb_serial_driver, not a
struct usb_driver. This is not a runtime bug, because the function
is an empty stub and never dereferences the passed pointer anyway.

Two of the CDC ACM control requests in the serial gadget have never
been correct, and have been reported to cause serious troubles ... as
in, soft lockup and maybe watchdog reset (depending on hardware).
This patch makes those request fail cleanly, rather than misbehaving.
Someone using CDC ACM should fix them according to the FIXME comments
which now replace the previous bugs.

I would like have the attached patch added to Linux kernel. The three
usb flash memories listed in the patch are being used in Intel's
ClassmatePC and need USB_QUIRK_RESET_RESUME to work reliably when
resuming from ram.
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.
Typical kernel log showing the problem is:
usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6
This patch works around the device limitation by adding "Rockchip ROCK MP3"
to unusual USB devices list and limiting data transfers to 64 sectors (32kB)
per command.
Tested on 2.6.23-rc5 (amd64).

A hardware bug was revealed after a recent PCI MSI patch was made to
always disable legacy INTX when enabling MSI. The 5714/5780 chips
will not generate MSI when INTX is disabled, causing MSI failure
messages to be reported, and another patch was made to workaround the
problem by disabling MSI on ServerWorks HT1000 bridge chips commonly
found with the 5714.
We workaround this chip bug by enabling INTX after we enable MSI and
after we resume from suspend.
Update version to 3.81.

i2c-algo-bit: Read block data bugfix
i2c-pxa: Fix adapter number
i2c-gpio: Fix adapter number
This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN,
used to implement i2c_smbus_read_block_data(). Previously, in the
absence of PEC (rarely used!) it would NAK the "length" byte:
S addr Rd [A] [length] NA
That prevents the subsequent data bytes from being read:
S addr Rd [A] [length] { A [data] }* NA
The primary fix just reorders two code blocks, so the length used
in the "should I NAK now?" check incorporates the data which it
just read from the slave device.
However, that move also highlighted other fault handling glitches.
This fixes those by abstracting the RX path ack/nak logic, so it
can be used in more than one location. Also, a few CodingStyle
issues were also resolved.

Problem:
A recovery thread must not be active when device is removed.
In qeth_remove_device() an interruptible wait operation is used
to wait until a qeth recovery thread is finished. If a user really
interrupts the ungroup operation of a qeth device while a recovery
is running, cio and qeth are out of sync (device already removed
from cio, but kept in qeth). A following module unload of qeth
results in a kernel OOPS here.

Update various SPI drivers so they properly support
- coldplug through "modprobe $(cat /sys/devices/.../modalias)"
- hotplug through "modprobe $(MODALIAS)"
The basic rule for platform, SPI, and (new style) I2C drivers is just
to make sure that modprobing the driver name works. In this case, all
the relevant drivers are platform drivers, and this patch either
(a) Changes the driver name, if no in-tree code would break;
this is simpler and thus preferable in the long term.
(b) Adds MODULE_ALIAS directives, when in-tree platforms declare
devices using the current driver name; less desirable.
Most systems will link SPI controller drivers statically, but
there's no point in being needlessly broken.

If the stack pointer is 0xc057a000, then the first stack page is at
0xc0579000 (the stack pointer is decremented before use). Not
calculating this correctly caused guests with CONFIG_DEBUG_PAGEALLOC=y
to be killed with a "bad stack page" message: the initial kernel stack
was just proceeding the .smp_locks section which
CONFIG_DEBUG_PAGEALLOC marks read-only when freeing.

ACPI 1.0 used an RSDT with 32-bit physical addresses.
ACPI 2.0 adds an XSDT with 32-bit physical addresses.
An ACPI 2.0 aware OS is supposed to use the XSDT
(when present) instead of the RSDT.
However, several systems have failed because the XSDT
contains NULL entries -- while it is missing pointers
to needed tables, such as SSDTs.
When we find an XSDT with NULL entries, discard it
and use the ACPI 1.0 RSDT instead.

Git changeset 6bdcc6e6db dropped the
stand-alone lgh06xf module, whose functionality was absorbed into the
dvb-pll module. However, there was a minor difference between the code
in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop
devices using the LG-H06xF NIM.
dvb-pll will probe for the presence of an i2c pll chip by performing a
single byte read, the lgh06xf driver did not do this. Unfortunately, the
code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads
as a probe. Such probes with the current code will always fail.
In order to work around this problem, and restore proper functionality
of the Airstar HD5000 device, this hack was created to make the probe
appear to succeed. The single byte read in dvb_pll_attach is the only
place where such a probe would ever occur, so this change is safe, and
will not affect any other devices.
Of course, if one knew how to actually perform the read operation, it
would be better to go that route. In the meantime, however, we must
apply this workaround, in order to prevent the regression that causes
tuning to fail on the Airstar HD5000 ATSC device.
Thanks to Jarod Wilson, who had originally reported this regression, and
to Geoffrey Hausheer, whose original workaround patch led us to find the
actual cause of the problem.

Previously I reported that the pata_pdc2027x PLL detection changes
in kernel 2.6.22 broke the driver on my PowerMac:
>pata_pdc2027x: Invalid PLL input clock 1691742kHz, give up!
This is followed by a number of errors and speed reduction
steps on the affected ports.
There are two bugs in pata_pdc2027x's PLL detection code:
1. The PLL counter's start value is read before the chip is
put in "test mode". Outside of test mode the counter is
halted, and on the PowerMac the counter is zero because
the chip hasn't been initialised by its BIOS.
The fix is to move the read of the start value to after
test mode is started, but before the mdelay() in test mode.
This also improves the precision of the PLL detection.
2. The code to compute the number of PLL decrements during the
mdelay() in test mode fails to consider that the PLL counter
only is 30 bits wide. If there is a wraparound, it will compute
an incorrect and much too large value. On the PowerMac, the
start count is zero, the end count is a large 30-bit value, so
wraparound occurs and an out of bounds PLL clock is detected.
The fix is to mask the (start - end) computation to 30 bits.
While debugging this I also noticed that pdc_read_counter()
reads the two halves of the 30-bit PLL counter as 16-bit values,
and then combines them as if the halves only are 15 bits wide.
To avoid confusion, the halves should be read as 15-bit values.
This patch implements all three changes. It fixes the PLL detection
failure on my PowerMac, and doesn't cause any regressions on an x86
with an identical card.

Ok, lets kill the message. As Alois Nešpor also saw, that's fixed up by Yenta,
so PCI does not have to warn about it. PCI could still warn about it if
is_cardbus is 0 in that instance of pci_scan_bridge(), but so far I have
not seen a report where this would have been the case so I think we can
spare the kernel of that check (removes ~300 lines of asm) unless debugging
is done.
History: The whole check was added in the days before we had the fixup
for this in Yenta and pci=assign-busses was the only way to get CardBus
cards detected on many (not all) of the machines which give this warning.
In theory, there could be cases when this warning would be triggered and
it's not cardbus, then the warning should still apply, but I think this
should only be the case when working on a completely broken PCI setup,
but one may have already enabled the debug code in drivers/pci and the
patched check would then trigger.
I do not sign this off yet because it's completely untested so far, but
everyone is free to test it (with the #ifdef DEBUG replaced by #if 1 and
pr_debug( changed to printk(.
We may also dump the whole check (remove everything within the #ifdef from
the source) if that's perferred.
On Alois Nešpor's machine this would then (only when debugging) this message:
"PCI: Bus #0b (-#0e) is partially hidden behind transparent bridge #0a (-#0b)"
"partially" should be in the message on his machine because #0b of #0b-#0e
is reachable behind #0a-#0b, but not #0c-#0e.
But that differentiation is now moot anyway because the fixup in Yenta takes
care of it as far as I could see so far, which means that unless somebody
is debugging a totally broken PCI setup, this message is not needed anymore,
not even for debugging PCI.
Ok, here the patch with the following changes:
* Refined to say that the bus is only partially hidden when the parent
bus numbers are not totally way off (outside of) the child bus range
* remove the reference to pci=assign-busses and the plea to report it
We could add a pure source code-only comment to keep a reference to
pci=assign-busses the in case when this is triggered by someone who
is debugging the cause of this message and looking the way to solve it.

Recent versions of the Linux kernel auto-suspend attached USB devices.
After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints
don't seem to wake back up correctly, causing further use with libgphoto2
to fail with a -114 "OS error in camera communication" error.
A similar fix is probably necessary for this camera in PTP mode, which
identifies as USB product id 0x3102, but we haven't tested this.
As part of our testing process, we tried the USB_QUIRK_RESET_RESUME
quirk also, it's not helpful in this case.

Correctly initialize the on-chip EHCI controller on the AMCC PPC440EPx.
Fix "USB 0.0" initialization message, and properly put the controller
into a known state before starting it.
Add "FIXME" comment to the au1xxx bus glue which is doing the same wrong
thing here. (Who maintains that, now that AMD sold off Alchemy?) Remove
some false copyright attributions which were somehow placed in the au1xxx
bus glue then copied into ppc-soc.

Kim Liu found that in the original code certain class setup requests
are wrongly recognized and processed as standard setup requests.
For that reason gadget ether can't work in RNDIS mode with Windows host.
The patch fixes the setup request processing code, and makes class
requests correctly passed to gadget layer.

the pwc driver has a disconnect method that waits for user space to
close the device. This opens up an opportunity for a DoS attack,
blocking the USB subsystem and making khubd's task busy wait in
kernel space. This patch shifts freeing resources to close if an opened
device is disconnected.

it seems like you overdid it a bit in your quest to clean up the
use of urb->status. In this driver you read it the first thing, which
means that you are in a race against URB completion you'll
usually lose, returning -EINPROGRESS. This kills the driver.

This patch (as961) fixes a couple of bugs in the disconnect pathway of
usb-storage.
The first problem, which apparently has been around for a while
although nobody noticed it, shows up when an aborted command is still
pending when a disconnect occurs. The SCSI error-handler will
continue to wait in command_abort() until the us->notify completion is
signalled. Thus quiesce_and_remove_host() needs to signal it.
The second problem was introduced recently along with autosuspend
support. Since usb_stor_scan_thread() now calls
usb_autopm_put_interface() before exiting, we can't simply leave the
scanning thread running after a disconnect; we must wait until the
thread exits. This is solved by adding a new struct completion to the
private data structure. Fortuitously, it allows the removal of the
rather clunky mechanism used in the past to insure that all threads
have finished before the module is unloaded.

Some devices have a bug which causes them to send a 1-byte reply to
Get-Device-Status requests instead of 2 bytes as required by the
spec. This doesn't play well with autosuspend, since we look for a
valid status reply to make sure the device is still present when it
resumes. Without both bytes, we assume the device has been
disconnected.
Lack of the second byte shouldn't matter much, since the spec requires
it always to be equal to 0. Hence this patch (as959) causes
finish_port_resume() to accept a 1-byte reply as valid.

If, in em28xx_usb_probe() the memory allocation
dev->alt_max_pkt_size = kmalloc(32*
dev->num_alt,GFP_KERNEL);
fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated
to 'dev', thus causing a memory leak.
This patch fixes the leak by freeing 'dev' before we return -ENOMEM.
This fixes Coverity bug #647.

The attached (mostly trivial) patches adds support for the Evolution
Scorpion Robots.
Evolution Robotics supplies a patch against 2.6.8 with their
software. My patch is based on their work, so I don't know if I can
sign it off, or if you need some Evolution people to do this (which
might be hard).
The patch adds device ID's for some robots which is trivial.
