3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me 
know.

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

From: Wolfram Sang <wsa+rene...@sang-engineering.com>

commit 36d48fb5766aee9717e429f772046696b215282d 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.
