Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6: (365 commits) ALSA: hda - Disable sticky PCM stream assignment for AD codecs ALSA: usb - Creative USB X-Fi volume knob support ALSA: ca0106: Use card specific dac id for mute controls. ALSA: ca0106: Allow different sound cards to use different SPI channel mappings. ALSA: ca0106: Create a nice spot for mapping channels to dacs. ALSA: ca0106: Move enabling of front dac out of hardcoded setup sequence. ALSA: ca0106: Pull out dac powering routine into separate function. ALSA: ca0106 - add Sound Blaster 5.1vx info. ASoC: tlv320dac33: Use usleep_range for delays ALSA: usb-audio: add Novation Launchpad support ALSA: hda - Add workarounds for CT-IBG controllers ALSA: hda - Fix wrong TLV mute bit for STAC/IDT codecs ASoC: tpa6130a2: Error handling for broken chip ASoC: max98088: Staticise m98088_eq_band ASoC: soc-core: Fix codec->name memory leak ALSA: hda - Apply ideapad quirk to Acer laptops with Cxt5066 ALSA: hda - Add some workarounds for Creative IBG ALSA: hda - Fix wrong SPDIF NID assignment for CA0110 ALSA: hda - Fix codec rename rules for ALC662-compatible codecs ALSA: hda - Add alc_init_jacks() call to other codecs ...
