Merge series "ALSA: hda: export snd_hda_codec_cleanup()" from Kai Veh…

…manen <kai.vehmanen@linux.intel.com>:

Hi,

this small series is preparation for a set of bugfix ASoC patches
addressing a memleak at module unload for the HDA codec wrapper.
Instead of duplicating HDA code in ASoC tree, I chose to export
more functionality from hda_codec.c so it can be (re)used in ASoC's
hdac_hda.c.

Full series:
https://github.com/thesofproject/linux/pull/2252

Takashi and Mark, feedback is welcome on how to best handle this
kind of series where I have dependent patches both in sound/pci/hda
and in ASoC. For this series, I'm sending the patches separately
and when/if first set is merged by Takashi, I'll route the ASoC
patches via our usually SOF set to Mark.
