Subject: ASoC: rsnd: rsnd_ssi_run_mods() needs to care ssi_parent_mod

From: Kuninori Morimoto <[email protected]>

[ 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.
