Subject: ASoC: rsnd: rsnd_ssi_run_mods() needs to care ssi_parent_mod
From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
[ Upstream commit 21781e87881f9c420871b1d1f3f29d4cd7bffb10 ]
SSI parent mod might be NULL. ssi_parent_mod() needs to care
about it. Otherwise, it uses negative shift.
This patch fixes it.
