3.16.7-ckt20 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Wolfram Sang <wsa+rene...@sang-engineering.com>
commit eadd709f5d2e8aebb1b7bf49460e97a68d81a9b0 upstream.
The core may register clients attached to this master which may use
funtionality from the master. So, RuntimePM must be enabled before, otherwise
this will fail. While here, move drvdata, too.
