2009-01-02V4L/DVB (10163): em28xx: allocate adev together with struct em28xx devMauro Carvalho Chehab1-50/+41
Some devices require different setups on struct_audio. Due to that, we may need to change some fields at dev.adev during device probe. So, this patch moves the dynamic memory allocation of adev at em28xx-alsa to the dynamic allocation of struct em28xx dev that happens during device probe.

2008-12-29V4L/DVB (9588): Don't load em28xx audio module for digital-only devicesDevin Heitmueller1-4/+6
Rework the logic so that the em28xx-alsa module does not get loaded for devices that don't support analog audio (such as the em2874) Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-01em28xx: remove backward compat macro added on a previous fixMauro Carvalho Chehab1-12/+0
commit 50f3beb50abe0cc0228363af804e50e710b3e5b0 fixed em28xx-alsa locking schema. However, a backport macro was kept. This patch removes the macro, since it is not needed for the module compilation against upstream. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-01V4L/DVB (9743): em28xx: fix oops audioDouglas Schilling Landgraf1-1/+1
Replaced usb_kill_usb for usb_unlink_usb (wait until urb to fully stop require USB core to put the calling process to sleep).

2008-11-24V4L/DVB (9742): em28xx-alsa: implement another locking schemaMauro Carvalho Chehab1-13/+24
Instead of using a spinlock, it is better to call the proper pcm stream locking schema. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-06-26V4L/DVB (8026): Avoids an OOPS if dev struct can't be successfully recoveredMauro Carvalho Chehab1-0/+6
On some alsa versions, it seems that snd_pcm_substream_chip(substream) is returning a NULL pointer. This causes an OOPS, as reported by: https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/212271 https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/212960 This patch avoids the OOPS by not letting and open() succeed.

2008-06-26V4L/DVB (8017): Ensure em28xx extensions only get run against devs that support themDevin Heitmueller1-0/+12
em28xx-audio.c em28xx-dvb.c - Em28xx extensions should ensure they are being only loaded against devices that support them. Deals with case where there are multiple em28xx devices, some of which have DVB (or ALSA) support and some do not.

2008-01-25V4L/DVB (6952): Add code for autoloading em28xx-alsa, if neededMauro Carvalho Chehab1-1/+0
Older em28xx devices does implement standard Audio Class. However, on newer devices, this were replaced by a Vendor Class. This patch autodetects that an em28xx lacks Audio Class and auto-loads em28xx-alsa, for the devices that implements only a Vendor Class. For devices with Audio Class, snd-usb-audio module will provide an ALSA interface. This patch uses the request_module_async function as defined on cx88-mpeg.c, originally wrote by Markus Rechberger.

2008-01-25V4L/DVB (6949): Adds em28xx-audio moduleMarkus Rechberger1-0/+474
em28xx-audio module exports em28xx Vendor Class audio as an -alsa driver. This module were written based on usbaudio driver by Markus Rechberger. Recently, he acked to allow us to merge it on kernel: http://lists-archives.org/video4linux/20408-supporting-prolink-pixelview-405-dvd-maker.html Thanks to Markus Rechberger <mrechberger@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
