media: au0828: Only alt setting logic when needed

2014-09-17T16:19:05+00:00

commit 64ea37bbd8a5815522706f0099ad3f11c7537e15 upstream.

It seems that there's a bug at au0828 hardware/firmware
related to alternate setting: when the device is already at
alt 5, a further call causes the URBs to receive -ESHUTDOWN.

I found two different encarnations of this issue:

1) at qv4l2, it fails the second time we try to open the
video screen;
2) at xawtv, when audio underrun occurs, with is very
frequent, at least on my test machine.

The fix is simple: just check if alt=5 before calling
set_usb_interface().

media: hdpvr: fix two audio bugs

2014-07-31T19:52:53+00:00

commit 3445857b22eafb70a6ac258979e955b116bfd2c6 upstream.

When the audio encoding is changed the driver calls hdpvr_set_audio
with the current opt->audio_input value. However, that should have
been opt->audio_input + 1. So changing the audio encoding inadvertently
changes the input as well. This bug has always been there.

The second bug was introduced in kernel 3.10 and that broke the
default_audio_input module option handling: the audio encoding was
never switched to AC3 if default_audio_input was set to 2 (SPDIF input).

In addition, since starting with 3.10 the audio encoding is always set
at the start the first bug now always happens when the driver is loaded.
In the past this bug would only surface if the user would change the
audio encoding after the driver was loaded.

Also fixes a small trivial typo (bufffer -> buffer).

media: uvcvideo: Fix clock param realtime setting

2014-07-01T03:11:59+00:00

commit 3b35fc81e7ec552147a4fd843d0da0bbbe4ef253 upstream.

timestamps in v4l2 buffers returned to userspace are updated in
uvc_video_clock_update() which uses timestamps fetched from
uvc_video_clock_decode() by calling unconditionally ktime_get_ts().

Hence setting the module clock param to realtime has no effect before
this patch.

This has been tested with ffmpeg:

ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 30 -i /dev/video0 \
 -f alsa -acodec pcm_s16le -ar 16000 -ac 1 -i default \
 -c:v libx264 -preset ultrafast \
 -c:a libfdk_aac \
 out.mkv

and inspecting the v4l2 input starting timestamp.

media: stk1160: Avoid stack-allocated buffer for control URBs

2014-07-01T03:11:58+00:00

commit 85ac1a1772bb41da895bad83a81f6a62c8f293f6 upstream.

Currently stk1160_read_reg() uses a stack-allocated char to get the
read control value. This is wrong because usb_control_msg() requires
a kmalloc-ed buffer.

This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
the read value.

While here, let's remove the urb_buf array which was meant for a similar
purpose, but never really used.
