Luis Henriques Sept. 30, 2013, 10:10 a.m. -stable review patch.  If anyone has any objections, please let me know.


From: Johannes Berg <johannes.berg@intel.com>

commit 707aee401d2467baa785a697f40a6e2d9ee79ad5 upstream.

The BT_CONFIG command that is sent to the device during
startup will enable BT coex unless the module parameter
turns it off, but on devices without Bluetooth this may
cause problems, as reported in Redhat BZ 885407.

Fix this by sending the BT_CONFIG command only when the
device has Bluetooth.
