ASoC: rsnd: check src mod pointer for rsnd_mod_id()
commit 374503c6109e60f48fa9b11341b14466f07bd3f4 upstream.
Without this patch, gcc 4.9.x says
sound/soc/sh/rcar/cmd.c: In function 'rsnd_cmd_init':
sound/soc/sh/rcar/cmd.c:85:14: warning: array subscript is below array\
bounds [-Warray-bounds]
data = path[rsnd_mod_id(src)] |
