2008-12-31em28xx: allocate adev together with struct em28xx devMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> 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.

2008-06-14Avoids an OOPS if dev struct can't be successfully recoveredMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> 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.

Ensure em28xx extensions only get run against devs that support them 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.

2008-01-05Add code for autoloading em28xx-alsa, if neededMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> 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. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
