3.16.55-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Maciej S. Szmigiero" <mail@xxxxxxxxxxxxxxxxxxxxx>
commit 04143d614f3af84a3f39e79a24a7ca740bd39efd upstream.
Check whether setting AC'97 ops succeeded and clean them
on removal so the fsl_ssi driver can be reloaded.
