From: Vinod Koul <vinod.koul@intel.com>

This patch add support for various modules like eq etc for mrfld DSP. All these
modules will be exposed to usermode as bytes controls.

Better to use simply WARN() for the condition and the message.

Superfluous error message (in other places, too).

Shouldn't this be bc->type?
