The uvcvideo driver's uvc_v4l2_open() method is called from videodev's
video_open() function, which means it is called with the videodev_lock
mutex held. uvc_v4l2_open() then takes uvc_driver.open_mutex to check
dev->state and avoid racing against a device disconnect, which means
that open_mutex must nest inside videodev_lock.
However uvc_disconnect() takes the open_mutex around setting
dev->state and also around putting its device reference. However, if
uvc_disconnect() ends up dropping the last reference, it will call
uvc_delete(), which calls into the videodev code to unregister its
device, and this will end up taking videodev_lock. This opens a
(unlikely in practice) window for an AB-BA deadlock and also causes a
lockdep warning because of the lock misordering.
Fortunately there is no apparent reason to hold open_mutex when doing
kref_put() in uvc_disconnect(): if uvc_v4l2_open() runs before the
state is set to UVC_DEV_DISCONNECTED, then it will take another
reference to the device and kref_put() won't call uvc_delete; if
uvc_v4l2_open() runs after the state is set, it will run before
uvc_delete(), see the state, and return immediately -- uvc_delete()
does uvc_unregister_video() (and hence video_unregister_device(),
which is synchronized with videodev_lock) as its first thing, so there
is no risk of use-after-free in uvc_v4l2_open().
Bug diagnosed based on a lockdep warning reported by Romano Giannetti

A number of V4L drivers have a mod param to specify their preferred minors.
This is because it is often desirable for applications to have a static /dev
name for a particular device. However, using minors has several disadvantages:
1) the requested minor may already be taken
2) using a mod param is driver specific
3) it requires every driver to add a param
4) requires configuration by hand
This patch introduces an "index" attribute that when combined with udev rules
can create static device paths like this:
/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0
/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video1
/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video2
$ ls -la /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0
lrwxrwxrwx 1 root root 12 2008-04-28 00:02 /dev/v4l/by-path/pci-0000:00:1d.2-usb-0:1:1.0-video0 -> ../../video1
These paths are steady across reboots and should be resistant to rearranging
across Kernel versions.
video_register_device_index is available to drivers to request a
specific index number.

Back in the early days of the pvrusb2 driver, the kernel class
mechanism in use for the sysfs interface had no means to pass
per-attribute information to the show / store functions. This forced
me to implement a horrible ugly thunking mechanism (i.e. infer the
missing data through the use of dedicated cookie cutter bounce
functions). However now we're using a better mechanism which also
passes enough additional information to the show / store functions
that we no longer need the hack. So eliminate all the crap. Yay!

The pvrusb2 driver initially sets the tuner to known broadcast frequencies
in the Chicago area, to ease driver testing for the maintainer.
This patch keeps those default frequencies, but allows them to be altered
via modprobe option. This allows the same ease and convenience for testing
multiple pvrusb2 devices one after another under other conditions and areas.
For instance, the default initial frequency, 175.25 MHz, might not
necessarily be valid on all cable television networks, but usually will be a
valid NTSC broadcast channel.

Cortland Setlow pointed out a bug in ov7670.c where the result from
ov7670_read() was just being checked for !0, rather than <0. This made me
realize that ov7670_read's semantics were rather confusing; it both fills
in 'value' with the result, and returns it. This is goes against general
kernel convention; so rather than fixing callers, let's fix the function.
This makes ov7670_read return <0 in the case of an error, and 0 upon
success. Thus, code like:
res = ov7670_read(...);
if (!res)
goto error;
..will work properly.

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).
Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.
This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

When an error occurs at firmware loading, sometimes, tda1004x stops answering.
Instead of reporting such error, attach code were assuming that the device were

tda1004x: tda1004x_read_byte: reg=0x0
tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5

the reason is another kconfig tool bug that has to be worked around in
the driver's Kconfig file: if FW_LOADER is selected in a second
dependency, that is not properly propagated up the dependencies.
in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028:
config MEDIA_TUNER_XC2028
tristate "XCeive xc2028/xc3028 tuners"
depends on VIDEO_MEDIA && I2C
depends on HOTPLUG
select FW_LOADER
which got selected by MEDIA_TUNER:
config MEDIA_TUNER
tristate
default VIDEO_MEDIA && I2C
depends on VIDEO_MEDIA && I2C
select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG
but the kconfig tool did not pick up this second-order dependency and
allowed CONFIG_FW_LOADER=m to be selected - in which case the build
fails.
the workaround i found was to move the select of FW_LOADER one level up,
so that the buggy kconfig tool can notice it and can act appropriately.
This problem can probably be worked around in other ways as well, i went
for the minimal fix.
Obviously, the kconfig tool should be fixed, it is not reasonable to
expect driver authors to do manual dependency resolution (that kconfig
itself already does) and uglify the Kconfig files. The kconfig tool did
nothing to warn about this situation and did not prevent this faulty
.config from being constructed.
