[alsa-devel] [PATCH 03/16] ASoC: Intel: Skylake: Add helper routine to handle Algo parameter

[Vinod Koul]

From: Jeeja KP <jeeja.kp at intel.com>

Some DSP modules has user configurable parameters, which are
required by some modules at module initialization.

To configure the module algorithm parameter during initialization
we add helpers here
