Subject: [PATCH 3.15 64/66] ALSA: hda - hdmi: call overridden init on resume

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pierre Ossman <pierre@...man.eu>

commit a283368382c50345dff61525f493ea307f21ec9b upstream.

We need to call the proper init function in case it has been
overridden, as it might restore things that the generic routing
doesn't know anything about. E.g. AMD cards have special verbs
that need resetting.
