The coverity checker detected a use-after-free error in drivers/media/video/cpia2/cpia2_v4l.c::cpia2_close() (coverity error #1281). What happens is that we lock cam->busy_lock, then proceed to free resources, and in the case of (--cam->open_count == 0) we finish off by doing a kfree(cam) and then at the end of the function we do a mutex_unlock(&cam->busy_lock) which will explode since it'll dereference the free'd `cam' : ... mutex_lock(&cam->busy_lock); ... if (--cam->open_count == 0) { ... if (!cam->present) { video_unregister_device(dev); kfree(cam); } } mutex_unlock(&cam->busy_lock); <--- PROBLEM, cam no longer around. ... Since this only happens in the case of open_count going down to zero I don't see a problem with just releasing the mutex after unregistering the device and just before the kfree(). In this case there is nothing around that we can race against; we are in the release method, open_count is zero, (!cam->present) and the device has just been unregistered, so letting go of the mutex at this point looks safe to me. Patch below to implement that solution. Acked-by:Randy Dunlap <rdunlap@xenotime.net> Signed-off-by:

There's a call at cx88-tvaudio to reset DMA sound on channel change; that call was killing cx88-alsa whenever the channel was changed, resulting in no sound. Remove those calls if cx88-alsa is selected to be compiled. Signed-off-by:

cx88-alsa was resetting the card on load, causing the IRQ IR handler to go away (maybe others, too). There's no actual need to reset the card, though, so that line was removed Signed-off-by:

There was an unmasked bit in the keycodes that was causing random behaviour (the code could be N or N+1). Masked that bit now. Signed-off-by:

This Kconfig description is incorrect, due to a previous merge a while back. CONFIG_SAA711X builds module saa7115, which is the newer module, and is not obsoleted. Signed-off-by:

Add detection for the LifeView3000 NTSC model (right now the PAL version is the only one in there, which is sort of annoying for me living in the US and all.. sigh...) This is one of those things that I like to classify "as a works for me so take it or leave it" :-) . Not that worried because its an $18 video capture card that didn't look it was selling to well in the US, but then again who knows. The documentation needs updating too I bet but its behind anyways usually to what is in the code. Signed-off-by:
