Merge tag 'sound-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There are no too intrusive changes in this update batch. The biggest LOC is found in the new DICE driver, and other small changes are scattered over the whole sound subtree (which is a common pattern). Below are highlights: - ALSA core: * Memory allocation support with genpool * Fix blocking in drain ioctl of compress_offload - HD-audio: * Improved AMD HDMI supports * Intel HDMI detection improvements * thinkpad_acpi mute-key integration * New PCI ID, New ALC255,285,293 codecs, CX20952 - USB-audio: * New buffer size management * Clean up endpoint handling codes - ASoC: * Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers from drivers. * A refresh of the documentation. * Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. * Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it. - Firewire: DICE driver - Lots of small fixes for bugs reported by Coverity" * tag 'sound-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (382 commits) ALSA: hda/realtek - Add new codec ALC255/ALC3234 UAJ supported ALSA: hda - Apply MacBook fixups for CS4208 correctly ASoC: fsl: imx-wm8962: remove an unneeded check ASoC: fsl: imx-pcm-fiq: Remove unused 'runtime' variable ALSA: hda/realtek - Make fixup regs persist after resume ALSA: hda_intel: ratelimit "spurious response" message ASoC: generic-dmaengine-pcm: Use SNDRV_DMA_TYPE_DEV_IRAM as default ASoC: dapm: Use WARN_ON() instead of BUG_ON() ASoC: wm_adsp: Fix BUG_ON() and WARN_ON() usages ASoC: Replace BUG() with WARN() ASoC: wm_hubs: Replace BUG() with WARN() ASoC: wm8996: Replace BUG() with WARN() ASoC: wm8962: Replace BUG() with WARN() ASoC: wm8958: Replace BUG() with WARN() ASoC: wm8904: Replace BUG() with WARN() ASoC: wm8900: Replace BUG() with WARN() ASoC: wm8350: Replace BUG() with WARN() ASoC: txx9: Use WARN_ON() instead of BUG_ON() ASoC: sh: Use WARN_ON() instead of BUG_ON() ASoC: rcar: Use WARN_ON() instead of BUG_ON() ...
