From: Steven Rostedt
Date: Wed Sep 11 2013 - 01:06:10 EST


3.6.11.9-rc1 stable review patch.
If anyone has any objections, please let me know.

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

From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx>

[ Upstream commit eca396d7a5bdcc1fd67b1b12f737c213ac78a6f4 ]

If device was put into a sleep and system was restarted or module
reloaded, we have to wake device up before sending other commands.
Otherwise it will fail to start with Microcode error.
