From 502c12e1ef14967e08dabb04c674cf0f000e8f7e Mon Sep 17 00:00:00 2001 From: Mohamed Abbas Date: Thu, 23 Oct 2008 23:48:54 -0700 Subject: [PATCH] iwlwifi: clear scanning bits upon failure In iwl_bg_request_scan function, if we could not send a scan command it will go to done. In done it does the right thing to call mac80211 with scan complete, but the problem is STATUS_SCAN_HW is still set causing any future scan to fail. Fix by clearing the scanning status bits if scan fails. Signed-off-by: Mohamed Abbas Signed-off-by: Reinette Chatre Signed-off-by: John W.
