9e87f22ac6 HID: multitouch: detect serial protocol
Microsoft's documentation about multitouch protocols tells that
if a device presents one touch per report, then it should be treated
as a serial protocol.

8d179a9ef2 HID: handle all multitouch devices through hid-multitouch
When the quirk HID_QUIRK_MULTITOUCH is present and when hid-multitouch
is loaded, let's pass the device to hid-multitouch even if it has
not been registered in hid-multitouch.

If any other driver wants to take precedence over hid-multitouch,
the usual way of adding it to hid_have_special_driver will work as
the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

ed9d5c9614 HID: multitouch: fix handling of buggy reports descriptors for Dell ST2220T
LG multitouch panels, such as the one found in Dell ST2220T, has buggy
reports descriptors. With the previous implementation, it was impossible
to rely on the reports descriptors to determine how the different
touches are emitted from the device.

This patch changes the splitting of the different touches in the report
in a more robust way.

fd1d152583 HID: multitouch: add more eGalax devices
This is a list of devices that should be handled by hid-multitouch.  They all
present the HID usage "Contact ID" and won't be handled by hid-input.  Some of
them have _not_ been tested (though I have their report descriptors), but I've
been guaranted by eeti that they follow the same protocol.  The tested ones are
also blacklisted in hid-core.c.

883e0e3662 HID: hid-input: allow array fields out of range
Allow array field values out of range as per HID 1.11 specification,
section 6.2.25:

	Rather than returning a single bit for each button in the group, an
	array returns an index in each field that corresponds to the pressed
	button (like keyboard scan codes). An out-of range value in and array
	field is considered no controls asserted.

Apparently, "and" above is a typo and should be "an".

This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never
released.

The relevant part of Waltop tablet report descriptors is this:

	0x09, 0x42,         /*          Usage (Tip Switch),         */
	0x09, 0x44,         /*          Usage (Barrel Switch),      */
	0x09, 0x46,         /*          Usage (Tablet Pick),        */
	0x15, 0x01,         /*          Logical Minimum (1),        */
	0x25, 0x03,         /*          Logical Maximum (3),        */
	0x75, 0x04,         /*          Report Size (4),            */
	0x95, 0x01,         /*          Report Count (1),           */
	0x80,               /*          Input,                      */

This is a regression fix for commit b4b583d ("HID: be more strict when
ignoring out-of-range fields").

e7747475b6 mmc: core: Fixup suspend/resume issues for UHS-I cards
Even if cards supports 1.8V I/O voltage those should anyway be
initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs.
Some eMMC and embedded SDIO devices are able to be initialized
at 1.8V as well, but it is better to be safe.

Do note that initialization in this context means that the card
has been completely powered off, otherwise the card will remain
at the last I/O voltage level that were negotitiated.

Due to the above being taken care of the suspend/resume issues
for UHS-I SD-cards has been fixed.

On a system with large pages (64k in my case), the following BUG is

[    2.338995] [<ffffffc0000bc308>] kthread+0x84/0x8c

This is because of a 64k request with a max_req_size of 64k-1 bytes.

The following patch fixes the problem by limiting the max_blk_count
such that max_blk_count * max_blk_size == max_req_size. I couldn't
pursuade the compiler to emit a shift instead of a div without encoding
the shift explicitly.

5b6b0ad6e5 mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5
On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the
SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION
command. This works for SD cards. However, with MMC cards
the MMC_SET_BLOCK_COUNT command is used instead, but this
needs the same handling. Fix MMC cards by testing for the
MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53
board with a Transcend MMC+ card and eMMC.

The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this
is a regression for these boards introduced in 3.0; it should
go to 3.0/3.1/3.2-stable.

c84f15aed2 mmc: core: fix regression: set default clock gating delay to 0
A recent commit "mmc: core: Use delayed work in clock gating framework"
(597dd9d79c) introduced a default 200ms delay before clock gating
actually takes place.  This means that every time an MMC interface
becomes idle it first stays on for 200ms before gating its clock. This
leads to increased power consumption and is therefore a clear regression.
This patch restores the original behaviour by setting the default delay
to 0. Users prioritising throughput over power efficiency can still
modify the delay via sysfs.

ef8781989a mmc: atmel-mci: don't use dma features when using DMA with no chan available
Some callbacks are set too early -- i.e. we can have dma capabilities but
we can't get a dma channel. So wait to get the dma channel before setting
callbacks and change logs consequently.

15d1ad0cc9 hwmon: (f75375s) Catch some attempts to write to r/o registers
It makes no sense to attempt to manually configure the fan in auto mode,
or set the duty cycle directly in closed loop mode.  The corresponding
registers are then read-only.  If the user tries it nonetheless, error out
with EINVAL instead of silently doing nothing.

b17d6561ac hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enable
The F75387 supports automatic fan control using either PWM duty cycle or
RPM speed values.  Make the driver detect the latter mode, and expose the
different modes in sysfs as per pwm_enable, so that the user can switch
between them.

The interpretation of the pwm_enable attribute for the F75387 is adjusted
to be a superset of those values used for similar Fintek chips which do
not support automatic duty mode, with 2 mapping to automatic speed mode,
and moving automatic duty mode to the new value 4.

Toggling the duty mode via pwm_enable is currently denied for the F75387,
as the chip then simply reinterprets the fan configuration register values
according to the new mode, switching between RPM and PWM units, which
makes this a dangerous operation.

This patch introduces a new pwm mode into the driver. This is necessary
because the new mode (automatic pwm mode, 4) may already be enabled by the
BIOS, and the driver should not break existing functionality. This was seen
on at least one board.

4eb05d562e virtio: balloon: leak / fill balloon across S4
commit e562966dba added support for S4 to
the balloon driver.  The freeze function did nothing to free the pages,
since reclaiming the pages from the host to immediately give them back
(if S4 was successful) seemed wasteful.  Also, if S4 wasn't successful,
the guest would have to re-fill the balloon.  On restore, the pages were
supposed to be marked freed and the free page counters were incremented
to reflect the balloon was totally deflated.

However, this wasn't done right.  The pages that were earlier taken away
from the guest during a balloon inflation operation were just shown as
used pages after a successful restore from S4.  Just a fancy way of
leaking lots of memory.

Instead of trying that, just leak the balloon on freeze and fill it on
restore/thaw paths.  This works properly now.  The optimisation to not
leak can be added later on after a bit of refactoring of the code.

a3d0e4aeca OMAPDSS: APPLY: make ovl_enable/disable synchronous
ovl->enable/disable are meant to be synchronous so that they can handle
the configuration of fifo sizes. The current kernel doesn't configure
fifo sizes yet, and so the code doesn't need to block to function (from
omapdss driver's perspective).

However, for the users of omapdss a non-blocking ovl->disable is
confusing, because they don't know when the memory area is not used
any more.

Furthermore, when the fifo size configuration is added in the next merge
window, the change from non-blocking to blocking could cause side
effects to the users of omapdss. So by making the functions block
already will keep them behaving in the same manner.

And, while not the main purpose of this patch, this will also remove the
compile warning:

78d3e00bb0 watchdog: fix error in probe() of s3c2410_wdt (reset at booting)
Probe function of s3c2410 watchdog calls request_irq before initializing
required value (wdt_count). This incurs resetting watchdog counter value
and watchdog-reboot during booting up.

This patch addresses such an issue by calling request_irq later.

Error handling in probe function and calling oder in remove function are
also revised accordingly.
