smiapp: Take mutex during PLL update in sensor initialisation

2015-01-27T15:52:32+00:00

commit f85698cd296f08218a7750f321e94607da128600 upstream.

The mutex does not serialise anything in this case but avoids a lockdep
warning from the control framework.

media: smiapp: Only some selection targets are settable

2014-12-16T17:09:42+00:00

commit b31eb901c4e5eeef4c83c43dfbc7fe0d4348cb21 upstream.

Setting a non-settable selection target caused BUG() to be called. The check
for valid selections only takes the selection target into account, but does
not tell whether it may be set, or only get. Fix the issue by simply
returning an error to the user.

media: V4L2: ov7670: fix a wrong index, potentially Oopsing the kernel from user-space

2014-06-07T20:25:40+00:00

commit cfece5857ca51d1dcdb157017aba226f594e9dcf upstream.

Commit 75e2bdad8901a0b599e01a96229be922eef1e488 "ov7670: allow
configuration of image size, clock speed, and I/O method" uses a wrong
index to iterate an array. Apart from being wrong, it also uses an
unchecked value from user-space, which can cause access to unmapped
memory in the kernel, triggered by a normal desktop user with rights to
use V4L2 devices.

media: wm8775: fix broken audio routing

2013-12-20T15:45:10+00:00

commit 3af41a337a5b270de3e65466a07f106ad97ad0c6 upstream.

Commit 5aa9ae5ed5d449a85fbf7aac3d1fdc241c542a79 inverted the mute control
state test in s_routing which caused the audio routing to fail. This broke
ivtv support for the Hauppauge video/audio input bracket (which adds additional
video and audio inputs) all the way back in kernel 2.6.36.
This fix fixes the condition and it also removes a nonsense check on the
balance control.

[media] s5c73m3: Fix off-by-one valid range checking for fie->index

2013-05-21T11:36:54+00:00

Current code uses fie->index as array subscript, thus the valid value range
is 0 ... ARRAY_SIZE(s5c73m3_intervals) - 1.

[media] s5c73m3: fix indentation of the help section in Kconfig

2013-04-25T19:20:09+00:00

The 'help' section of the Kconfig entry for this driver is missing
an extra alignment. That seems to violate what's stated at:
	Documentation/kbuild/kconfig-language.txt

Even if it works, the better is to add 2 extra spaces there, as
this is the common practice and helps human reading of the file.

Also, the way it is, it breaks backport trees.

oif and sensor subdev and both media entities are freed on
driver removal.
