BugLink: http://bugs.launchpad.net/bugs/877165 imx_pcm_new() calls imx_pcm_preallocate_dma_buffer() to allocate dma buffers according _only_ to cpu_dai parameters, and this is not true. A better way is to check out both cpu_dai and codec_dai. Signed-off-by: Eric Miao <eric.miao@linaro.org>

BugLink: http://bugs.launchpad.net/bugs/855281 Playback/capture rates should be configured before the SPDIF codec DAI is registered, according to the parameters that passed in by the platform data.

2011-11-06ALSA: hda - Revert the check of NO_PRESENCE pincfg default bitTakashi Iwai
The implementation on commit [08a1f5eb: ALSA: hda - Check NO_PRESENCE pincfg default bit] seems like a mis-interpretation of specification. The spec gives the reversed bit definition. But, following the spec also causes to change so many existing device configurations, thus we can't change it so easily for now. For 3.2-rc1, it's safer to revert this check (actually this patch comments out the code). We may re-introduced the fixed version once after the wider test-case coverages are done.

The regression-fix in 3.1 for the check of DMA-position validity caused yet another regression for CA0110. As usual, this hardware seems working only with LPIB properly.

2011-11-06ALSA: hda - Fix silent output regression with ALC861Takashi Iwai
The 3.1 kernel has a regression for ALC861 codec where no sound output is heard with the default setup. It's because the amps in DACs aren't properly unmuted while the output mixers are assigned only to pins. This patch fixes the missing initialization of DACs when no mixer is assigned to them.

2011-11-06ALSA: ua101: fix crash when unpluggingClemens Ladisch
If the device is unplugged while running, it is possible for a PCM device to be closed after the disconnect callback has returned. This means that kill_stream_urb() and disable_iso_interface() would try to access already-invalid or freed USB data structures. The function free_usb_related_resources() was intended to prevent this, but forgot to clear the affected variables.

2011-11-02ALSA: hda/realtek - Don't create alt-stream for capture when unnecessaryTakashi Iwai
When the driver finds multiple ADCs, it tries to create an alternative capture PCM stream. However, these secondary ADCs might be useless or in uncontrolled paths in some cases, e.g. when auto-mic or dynamic ADC-switching is enabled. Also, when only a single capture source is available, the multi-streams don't make sense, too. With this patch, the driver checks such condition and skips the alt stream appropriately.

2011-10-31ALSA: intel8x0: Improve performance in virtual environmentKonstantin Ozerkov
v3: detection code is x86 and KVM specific, hide it under ifdef v2: add detection for virtual environments (KVM and Parallels) This patch is intended to improve performance in virtualized environments like Parallels Desktop or KVM/VirtualBox/QEMU (virtual ICH/AC97 audio). I/O access is very time-expensive operation in virtual world: VCPU can be rescheduled and in the worst case we get more than 10ms delay on each I/O access. In the virtual environment loop exit rule (old_civ == current_civ && old_picb == current_picb) is never satisfied, because old_picb is never the same as current_picb due to delay inspired by reading current_civ. As a result loop ended by timeout and we get 10x more I/O operations.
