Merge tag 'sound-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Again the diffstat shows a widely distributed pattern at this cycle, as there've been many code cleanups and refactoring allover the places. Other than that, the development was relatively calm, and no big surprise shouldn't be expected. Here are some highlights: Core: - Sequencer code refactoring / documentation updates - TLV code moved to uapi, following some relevant cleanups USB-Audio: - Lots of LINE6 driver fixes / updates - DragonFly and TEAC device quirk updates HD-audio: - Usual fixupes for Dell, Lenovo and HP machines - Link-audio time reporting capability ASoC: - Large refactoring of simple-card code to be shared with rcar driver - Removal of some duplicated ops over lots of CODEC drivers - Again quite a few Intel SKL driver updates - New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663" * tag 'sound-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (465 commits) ASoC: fsl: Fix lockups with recent cache changes ASoC: Intel: Skylake: fix memory leak of module on error exit path ASoC: rsnd: add SNDRV_PCM_TRIGGER_SUSPEND/RESUME ASoC: wm8960: remove usage of obsoleted TLV-related macro ASoC: rt5616: remove usage of obsoleted TLV-related macro ASoC: max9867: remove usage of obsoleted TLV-related macro ASoC: trivial: system spelling fix ASoC: da7219: fix inappropriate condition statement ASoC: tlv320aic31xx: do not declare support for mono DAI ASoC: stac9766: fix wrong usage of DECLARE_TLV_DB_LINEAR() ASoC: wm8991: remove unused variable ASoC: wm8991: fix wrong usage of DECLARE_TLV_DB_LINEAR() ASOC: tpa6130a2: add static qualifier for file local symbols ASoC: sst-bxt-rt298: fix obsoleted initializers for array ASoC: sst-bxt-da7219_max98357a: fix obsoleted initializers for array ASoC: rt5616: add static qualifier for file local symbols ASoC: arizona: Add output power up/down delays for speaker path ASoC: arizona: Add debug prints for output power up/down times ALSA: hda - Add the top speaker pin config for HP Spectre x360 ASoC: Intel: Add DMIC channel constraint for bxt machine ...
