Merge tag 'sound-3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"The significant part here is a few security fixes for ALSA core
control API by Lars. Besides that, there are a few fixes for ASoC
sigmadsp (again by Lars) for building properly, and small fixes for
ASoC rsnd, MMP, PXA and FSL, in addition to a fix for bogus WARNING in
i915/HD-audio binding"
* tag 'sound-3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
ALSA: control: Make sure that id->index does not overflow
ALSA: control: Handle numid overflow
ALSA: control: Don't access controls outside of protected regions
ALSA: control: Fix replacing user controls
ALSA: control: Protect user controls against concurrent access
drm/i915, HD-audio: Don't continue probing when nomodeset is given
ASoC: fsl: Fix build problem
ASoC: rsnd: fixup index of src/dst mod when capture
ASoC: fsl_spdif: Fix integer overflow when calculating divisors
ASoC: fsl_spdif: Fix incorrect usage of regmap_read()
ASoC: dapm: Make sure register value is in sync with DAPM kcontrol state
ASoC: sigmadsp: Split regmap and I2C support into separate modules
ASoC: MMP audio needs sram support
ASoC: pxa: add I2C dependencies as needed
