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" * tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (284 commits) ALSA: vmaster: Fix the regression of missing vmaster hook call ALSA: hda - Add Dell SSID to support Headset Mic recording ASoC: adau1701: remove control_data assignment ASoC: adau1701: more direct regmap usage ASoC: ac97: fixup multi-platform AC'97 module build failure ASoC: pxa2xx: fixup multi-platform AC'97 build failures ASoC: tegra20-ac97: Remove unused variable ASoC: tegra20-ac97: Remove duplicate error message ALSA: usb-audio: Add Audio Advantage Micro II ASoC: tas5086: fix Mid-Z implementation ASoC: tas5086: fix TAS5086_CLOCK_CONTROL register size ALSA: Replace the magic number 44 with const ALSA: hda - Fix the max length of control name in generic parser ALSA: hda - Guess what, it's two more Dell headset mic quirks ALSA: hda - Yet another Dell headset mic quirk ALSA: hda - Add support for ALC5505 DSP power-save mode ASoC: mfld: Remove unused variable ALSA: usb-audio: add quirks for Roland QUAD/OCTO-CAPTURE ALSA: usb-audio: claim autodetected PCM interfaces all at once ALSA: usb-audio: remove superfluous Roland quirks ...
