V4L/DVB (13190): em28xx: fix panic that can occur when starting audio streaming Because the counters were not reset when starting up streaming, they would be reused from the previous run. This can result in cases such that when the second instance of streaming starts up, the "cnt" variable in em28xx_audio_isocirq() can end up being negative, resulting in attempting to write to memory before the start of runtime->dma_area (as well as having a negative number of bytes to copy).

It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

V4L/DVB (10659): em28xx: register device to soundcard for sysfs As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should set the struct device for the card before registering the card instance. This will add the correct /sys/class/sound/cardN/device symlink, so HAL can see the device and ConsoleKit sets its ACL permissions for the logged-in user. For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2), this patch fixes errors like: ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied when running mplayer as a normal user.

Since pre-emption is enabled then it is safe to de-allocate the memory if you first unlink each URB. In this instance you are safe since pre-emption is disabled. If pre-emption and irqs are not disabled then call usb_kill_urb(), else call usb_unlink_urb(). Thanks to Douglas for tracking down this bug originally!!!

V4L/DVB (8026): Avoids an OOPS if dev struct can't be successfully recovered 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.

V4L/DVB (8017): 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.

V4L/DVB (6952): Add code for autoloading em28xx-alsa, if needed 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.
