Subject: ASoC: SOF: Intel: add module namespace for legacy IPC
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f4483a0fda1df3e5b4f25de647b8777d2481f08c;p=linux.git

ASoC: SOF: Intel: add module namespace for legacy IPC

The legacy IPC routines are only used by broadwell and baytrail
modules, import them as needed and make sure other modules cannot load
them.
