4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej S. Szmigiero <mail@xxxxxxxxxxxxxxxxxxxxx>
commit 695b78b548d8a26288f041e907ff17758df9e1d5 upstream.
AC'97 ops (register read / write) need SSI regmap and clock, so they have
to be set after them.
We also need to set these ops back to NULL if we fail the probe.
