If anyone has any objections, please let me know. ------------------ From: Stanislaw Gruszka commit eca396d7a5bdcc1fd67b1b12f737c213ac78a6f4 upstream. 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.
