Merge tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"A relative calm release at this time with a flat diffstat. The only
significant change in the ALSA core side is the support for more than
32 card instances, configurable via kconfig. Other than that, in both
ASoC and other parts, mostly some improvements and fixes on the driver
side.
- hda: More quirks for ALC269-variants on Dell & co, VIA codec fixes
- hda: Haswell HDMI audio fixes, runtime PM improvements
- hda: Intel BayTrail support, ALC5505 DSP support
- es1968: MediaForte M56VAP support
- usb-audio: Improved support for Yamaha/Roland devices
- usb-audio: M2Tech hiFace, Audio Advantage Micro II support
- hdspm: wordclock fixes
- ASoC: Pending fixes for WM8962
- ASoC: Cleanups and fixes for Blackfin, SGTL5000 and UX500
- ASoC: Generalisation of the Bluetooth and HDMI stub drivers
- ASoC: SSM2518 and RT5640 codec drivers.
- ASoC: Tegra CPUs with RT5640 machine driver
- ASoC: AC'97 refactoring bug fixes
- ASoC: ADAU1701 driver fixes
- Clean up of *_set_drvdata() in a wide range of drivers"
