[ 053/108] ath9k: stop btcoex on device suspend

[Greg Kroah-Hartman]

From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

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

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

From: Rajkumar Manoharan <rmanohar@xxxxxxxxxxxxxxxx>

commit e19f15ac6437624b6214b2f0ec0d69fb7eb205fa upstream.

During suspend, the device will be moved to FULLSLEEP state.
As btcoex is never been stopped, the btcoex timer is running
and tries to access hw on fullsleep state. Fix that.
