[ 016/127] iwlwifi: mvm: Always use SCAN_TYPE_FORCED

From: Greg Kroah-Hartman
Date: Wed Jun 05 2013 - 18:09:15 EST


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

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

From: Ilan Peer <ilan.peer@xxxxxxxxx>

commit f70ed7b330ce769828d402f920fb13da6c13ea63 upstream.

The FW AUX framework does not handle well cases where time events
fail to be scheduled (and as a result issues assert 0x3330). Until
a proper fix is in place, WA this by always setting the scan type to
SCAN_TYPE_FORCED.
