[PATCH 1/4] ASoC: Intel: Clear stored Baytrail DSP DMA pointer before stream start

[PATCH 1/4] ASoC: Intel: Clear stored Baytrail DSP DMA pointer before stream start

[Jarkko Nikula]

Stored DSP DMA pointer must be cleared before starting the stream since
PCM pointer callback sst_byt_pcm_pointer() can be called before pointer is
updated. In that case last position of previous stream was wronly returned.

[PATCH 3/4] ASoC: Intel: Use devm_snd_soc_unregister_card

[Jarkko Nikula]

Simplify byt-rt5640.c and haswell.c machine drivers by using
devm_snd_soc_unregister_card(). Remove also needless dev_set_drvdata()
from byt_rt5640_probe() since snd_soc_register_card() does it too.

[PATCH 4/4] ASoC: Intel: byt-rt5640: Use card PM ops from core

[Jarkko Nikula]

Use card PM ops from ASoC core instead of defining custom PM ops here since
we are calling anyway common suspend/resume callbacks.

Applied all, thanks.  Please don't do things like sending a new version
of a single patch in the middle of a series - it just makes it harder to
follow what the current version of things is, especially if there's also
some discussion going on.
