[PATCH 5.15 071/667] ASoC: rsnd: care default case on rsnd_ssiu_busif_err_status_clear()

[Greg Kroah-Hartman]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

[ 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.
