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"
