Merge tag 'sound-4.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"We see various small fixes, but nothing looks too scary, all are small
gentle bug fixes:
- Most of changes are for ASoC codecs: Realtek, SGTL5000, TAS2552,
TLV320, WM8962
- A couple of dwc and imx-ssi fixes
- Usual oneliner HD-audio quirks
- An old emux synth code fix"
