[media] em28xx: fix check for audio only usb interfaces when changing the usb alternate setting · 0191a2a2

由 Frank Schaefer 提交于 1月 13, 2014

Previously, we've been assuming that the video endpoints are always at usb
interface 0. Hence, if vendor audio endpoints are provided at a separate
interface, they were supposed to be at interface number > 0.
Instead of checking for (interface number > 0) to determine if an interface
is a pure audio interface, dev->is_audio_only should be checked.

[media] em28xx: fix usb alternate setting for analog and digital video endpoints > 0 · 961717b4

由 Frank Schaefer 提交于 1月 13, 2014

The current code assumes that the analog + digital video endpoints are always at
interface number 0 when changing the alternate setting.
This seems to work fine for most existing devices.
However, at least the SpeedLink VAD Laplace webcam has the video endpoint on
interface number 3 (which fortunately doesn't cause any trouble because ist uses
bulk transfers only).
We already consider the actual interface number for audio endpoints, so
rename the the audio_ifnum variable and use it for all device types.
Also get get rid of a pointless (ifnum < 0) in em28xx-audio.

[media] drxk: remove the option to load firmware asynchronously · 4b819724

由 Mauro Carvalho Chehab 提交于 1月 13, 2014

The option to load firmware asynchronously were added due to
a requirement with a few versions of udev. It turns that this was
a bad idea and caused regressions on drxk-based devices.

So, we end by only letting the firmware to be loaded syncronously
everywhere.

So, let's remove the bad code.

[media] em28xx: push mutex down to extensions on .fini callback · ebbfbc20

由 Mauro Carvalho Chehab 提交于 1月 13, 2014

Avoid circular mutex lock by pushing the dev->lock to the .fini
callback on each extension.

As em28xx-dvb, em28xx-alsa and em28xx-rc have their own data
structures, and don't touch at the common structure during .fini,
only em28xx-v4l needs to be locked.

It seems that, on such arch, the includes from asm/ should be

this fix is trivial, apply it. Also, we generally put the

Stop the feed on a start feed error.  The stop feed is not always called
if start feed fails.  If the feed is not stopped on error, then the driver
will be stuck so that it can never start feeding again.

[media] media: s5p_mfc: remove s5p_mfc_get_node_type() function · b80cb8dc

由 Marek Szyprowski 提交于 12月 03, 2013

s5p_mfc_get_node_type() relies on get_index() helper function, which in
turn relies on video_device index numbers assigned on driver
registration. All this code is not really needed, because there is
already access to respective video_device structures via common
s5p_mfc_dev structure. This fixes the issues introduced by patch
1056e438 ("v4l2-dev: Fix race condition
on __video_register_device"), which has been merged in v3.12-rc1.
