Subject: [PATCH 124/129] ASoC: rsnd: don't use rsnd_mod_to_io() on
rsnd_ssi_xxx()
Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths
if it supports MIXer. In such case, mod <-> io is no longer 1:1
relationship. This patch removes rsnd_mod_to_io() from rsnd_ssi_xxx()
and related function.
