[alsa-devel] [PATCH 3/3] ASoC: Intel: Skylake: Support for multiple data blocks

[Subhransu S. Prusty]

From: Shreyas NC <shreyas.nc at intel.com>

Module init params are additional data block in the module private data.
Skylake driver doesn't yet have support to parse multiple data blocks if
it appears in private data. Add support for parsing of multiple data
blocks and module init params.
