[media] uvcvideo: quirk PROBE_DEF for Microsoft Lifecam NX-3000

2013-09-24T13:20:22+00:00

The camera doesn't implement GET_DEF on the video probe control and
can crash when it receives the request depending on timings. Set the
PROBE_DEF quirk to work around the problem.

[media] em28xx: fix assignment of the eeprom data

2013-09-03T12:24:20+00:00

Set the config structure pointer to the eeprom data pointer (data,
here eedata dereferenced) not the pointer to the pointer to
the eeprom data (eedata itself).

[media] hdpvr: fix iteration over uninitialized lists in hdpvr_probe()

2013-09-03T12:24:20+00:00

free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(),
but if something bad happens before that, error handling code calls hdpvr_delete(),
which contains iteration over the lists (via hdpvr_free_buffers()).
The patch moves the lists initialization to the beginning and by the way fixes
goto label in error handling of registering videodev.
Found by Linux Driver Verification project (linuxtesting.org).

[media] usbtv: Throw corrupted frames away

2013-09-03T12:24:19+00:00

Ignore out of order data and mark incomplete buffers as errored.
This gets rid of annoying flicker due to occassional garbage from hardware.

[media] usbtv: Fix deinterlacing

2013-09-03T12:24:19+00:00

The image data is laid out a bit more weirdly and thus needs more work to
properly interlace. What we get from hardware is V4L2_FIELD_ALTERNATE, but
since userspace support for it is practically nonexistent, thus we make
V4L2_FIELD_INTERLACED from it so that it's more easily interpreted.

[media] Fix build errors on usbtv when driver is builtin

2013-08-24T08:58:14+00:00

As reported by Fengguang Wu 

   drivers/built-in.o: In function `vb2_ioctl_streamon':
>> (.text+0x8d354): undefined reference to `video_devdata'
   drivers/built-in.o: In function `vb2_ioctl_streamoff':
>> (.text+0x8d397): undefined reference to `video_devdata'
   drivers/built-in.o: In function `vb2_ioctl_expbuf':
...

That happens when:
	CONFIG_VIDEO_DEV=y
	CONFIG_VIDEO_V4L2=m
	CONFIG_VIDEO_USBTV=y

As the core is module, usbtv should also be compiled as module.

2013-08-24T07:49:56+00:00

This is a camera with an ov518+ revision 0 bridge + ov7620ae sensor,
which appearently needs different handling then the Trust spacecam 320, which
has an ov518+ revision 2 + ov7620ae sensor. The Terracam USB Pro used to write
this patch has kindly been provided by
Dr. Tilmann Bubeck .
