Subject: [PATCH] sound: ppc: snd_ps3: Remove Unneeded variable: "ret"

This patch fixes below issue reported by coccicheck
sound/ppc/snd_ps3.c:631:5-8: Unneeded variable: "ret". Return "0" on
line 668

We cannot change return type of snd_ps3_pcm_trigger as it is registered
with snd_pcm_ops->trigger
