Pull sound fixes from Takashi Iwai: "Nothing too exciting as a new year's start here: most of fixes are for ASoC, a boot crash fix on OMAP for deferred probe, a few driver specific fixes (Intel, dwc, rockchip, rt5677), in addition to typo fixes in kerneldoc comments for PCM" * tag 'sound-3.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: pcm: Fix kerneldoc for params_*() functions ASoC: rockchip: i2s: fix maxburst of dma data to 4 ASoC: rockchip: i2s: fix error defination of transmit data level ASoC: Intel: correct the fixed free block allocation ASoC: rt5677: fixed rt5677_dsp_vad_put rt5677_dsp_vad_get panic ASoC: Intel: Fix BYTCR machine driver MODULE_ALIAS ASoC: Intel: Fix BYTCR firmware name ASoC: dwc: Iterate over all channels ASoC: dwc: Ensure FIFOs are flushed to prevent channel swap ASoC: Intel: Add I2C dependency to two new machines ASoC: dapm: Remove snd_soc_of_parse_audio_routing() due to deferred probe
