[ Upstream commit b1384d4c95088d01f4266237faabf165d3d605fc ]

commit cfb7b8bf1e2d66 ("ASoC: rsnd: tidyup rsnd_ssiu_busif_err_status_clear()") merged duplicate code, but it didn't care about default case, and causes smatch warnings.

smatch warnings: sound/soc/sh/rcar/ssiu.c:112 rsnd_ssiu_busif_err_status_clear() \ error: uninitialized symbol 'offset'. sound/soc/sh/rcar/ssiu.c:114 rsnd_ssiu_busif_err_status_clear() \ error: uninitialized symbol 'shift'.

This patch cares it.
