From: Abhijeet Kolekar Date: Fri, 12 Jun 2009 20:22:52 +0000 (-0700) Subject: iwlwifi/iwl3945: fix suspend resume association bug X-Git-Tag: firefly_0821_release~13604^2~75^2~12 X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=8a9b99267cb3b51d4e59693c03e1204d86b42445;p=firefly-linux-kernel-4.4.55.git iwlwifi/iwl3945: fix suspend resume association bug Patch fixes the following bugs at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2005 http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2007 If we suspend with an association and then resumed, we need to synchronize the active rxon with staging rxon, else we will get an error when iwl_alive_start try to commit rxon and staging is set to channel 0. Before going to suspend staging and active rxon are in sync. After resuming from the suspend, iwl_mac_start is called and it clears the staging rxon. Patch fixes the bug by not clearing the staging rxon in iwl_mac_start. Patch also adds similar fix to 3945. Signed-off-by: Abhijeet Kolekar Signed-off-by: Reinette Chatre Signed-off-by: John W.
