* ARM: tegra: remove <mach/dma.h>Stephen Warren2012-11-052-3/+0
| | | | | | | | | | | | | | | Remove includes of <mach/dma.h> from sound/soc; nothing from it is used. Remove include of <mach/dma.h> from mach-tegra/apbio.c; since the DMA transfers made by this file don't need flow-control with any peripheral, there's no need to set any slave ID. Once those changes are made, there are no remaining users of <mach/dma.h> so remove it. Drivers should get this information from device tree. This removal is necessary for single zImage.

* ALSA: ice1724: Fix rate setup after resumeTakashi Iwai2012-10-311-1/+6
| | | | | | | | | The rate isn't restored properly after resume since it's only set up in hw_params, and not in prepare callback. For fixing it, put the corresponding call to resume callback as well.

* ALSA: Avoid endless sleep after disconnectTakashi Iwai2012-10-306-1/+46
| | | | | | | | | When disconnect callback is called, each component should wake up sleepers and check card->shutdown flag for avoiding the endless sleep blocking the proper resource release. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Add a reference counter to card instanceTakashi Iwai2012-10-3010-32/+83
| | | | | | | | | | | | | For more strict protection for wild disconnections, a refcount is introduced to the card instance, and let it up/down when an object is referred via snd_lookup_*() in the open ops. The free-after-last-close check is also changed to check this refcount instead of the empty list, too.

* ALSA: usb-audio: Fix races at disconnectionTakashi Iwai2012-10-305-41/+79
| | | | | | | | | | | | | | | | | | | | | | | | | Close some races at disconnection of a USB audio device by adding the chip->shutdown_mutex and chip->shutdown check at appropriate places. The spots to put bandaids are: - PCM prepare, hw_params and hw_free - where the usb device is accessed for communication or get speed, in mixer.c and others; the device speed is now cached in subs->speed instead of accessing to chip->dev The accesses in PCM open and close don't need the mutex protection because these are already handled in the core PCM disconnection code. The autosuspend/autoresume codes are still uncovered by this patch because of possible mutex deadlocks. They'll be covered by the upcoming change to rwsem. Also the mixer codes are untouched, too. These will be fixed in another patch, too. Reported-by: Matthieu CASTET <matthieu.castet@parrot.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Because snd_card_free both reads the fields of its argument and kfrees its argments, the results of the second snd_card_free should be unpredictable.
