OTOH, rsrc-card is used for DPCM system. FE portion is constituted by CPU and dummy Codec, and BE is constituted by dummy CPU and Codec in DPCM system. Because of this, current rsrc-card is doing pointless method. It works well if FE/BE was 1:1, but not good for multi FE/BE. This patch cleanups rsrc-card driver for DPCM. and this is prepare for MIX support for Renesas sound driver.
