Merge tag 'sound-3.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Unfortunately this update became bigger than previous pull requests,
  which is almost a pattern in rc5-6.  But, the only obvious big changes
  are for the new Intel DSP ASoC drivers, so the impact must be fairly
  limited.

  Other than that, usual small fixes in various fields: HD-audio, ASoC
  core and ASoC fsl and codec drivers"
