[media] s2255drv: fix payload size for JPG, MJPEG

2014-11-21T17:46:25+00:00

length is the size of the buffer, not the payload. That's set using
vb2_set_plane_payload().

[media] usbvision-video: two use after frees

2014-10-24T11:30:14+00:00

The lock has been freed in usbvision_release() so there is no need to
call mutex_unlock() here.

[media] em28xx-input: NULL dereference on error

2014-10-24T11:28:12+00:00

We call "kfree(ir->i2c_client);" in the error handling and that doesn't
work if "ir" is NULL.

[media] v4l: uvcvideo: Fix buffer completion size check

2014-10-21T10:53:27+00:00

Commit e93e7fd9f5a3fffec7792dbcc4c3574653effda7 ("v4l2: uvcvideo: Allow
using larger buffers") reworked the buffer size sanity check at buffer
completion time to use the frame size instead of the allocated buffer
size. However, it introduced two bugs in doing so:

- it assigned the allocated buffer size to the frame_size field, instead
  of assigning the correct frame size

- it performed the assignment in the S_FMT handler, resulting in the
  frame_size field being uninitialized if the userspace application
  doesn't call S_FMT.

Fix both issues by removing the frame_size field and validating the
buffer size against the UVC video control dwMaxFrameSize.

[media] em28xx: fix uninitialized variable warning

2014-10-21T10:51:07+00:00

Fix this daily build warning:

In file included from build/media_build/v4l/em28xx-core.c:35:0:
build/media_build/v4l/em28xx-core.c: In function 'em28xx_audio_setup':

  ^
build/media_build/v4l/em28xx-core.c:507:6: note: 'vid' was declared here
  u32 vid;
      ^

As far as I can tell 'vid' can not really be used uninitialized here, but the code
is sufficiently complex that apparently gcc can't figure that out.

[media] anysee: make sure loading modules is const

2014-10-21T10:49:11+00:00

Make sure that loaded modules are const char strings so we don't
load arbitrary modules in the future, nor allow for format string
leaks in the module request call.

Pull media updates from Mauro Carvalho Chehab:

 - new IR driver: hix5hd2-ir

 - the virtual test driver (vivi) was replaced by vivid, with has an
   almost complete set of features to emulate most v4l2 devices and
   properly test all sorts of userspace apps

 - the as102 driver had several bugs fixed and was properly split into a
   frontend and a core driver.  With that, it got promoted from staging
   into mainstream

 - one new CI driver got added for CIMaX SP2/SP2HF (sp2 driver)

 - one new frontend driver for Toshiba ISDB-T/ISDB-S demod (tc90522)

 - one new PCI driver for ISDB-T/ISDB-S (pt3 driver)

 - saa7134 driver got support for go7007-based devices

 - added a new PCI driver for Techwell 68xx chipsets (tw68)

 - a new platform driver was added (coda)

 - new tuner drivers: mxl301rf and qm1d1c0042

 - a new DVB USB driver was added for DVBSky S860 & similar devices

 - added a new SDR driver (hackrf)

 - usbtv got audio support

 - several platform drivers are now compiled with COMPILE_TEST

 - a series of compiler fixup patches, making sparse/spatch happier with
   the media stuff and removing several warnings, especially on those
   platform drivers that didn't use to compile on x86

 - Support for several new modern devices got added

 - lots of other fixes, improvements and cleanups
