[alsa-devel] [PATCH 21/35] ASoC: Intel: Expose ACPI loading members

[Cezary Rojewski]

No framework should know upfront about specifics of its inheriting
members. sst-acpi contains Baytrail and Haswell specific data. In order
to prevent circular dependency, it's compiled into separate module.

Let's do it right and obey inheritance rule. As a first step, elevate
sst-acpi members so they could be shared by Haswell and
Baytrail-specific handlers - this is to prevent code duplication.
