From 282cdb325aea4ebbc42ce753b47cc96145eb54bc Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 12 Sep 2011 12:09:10 -0700 Subject: iwlagn: fix command queue timeout If the command queue is constantly busy, which can happen in P2P, the hangcheck timer will frequently find a command in it and will eventually reset the device because nothing sets the timestamp for this queue when commands are processed. Fix this by setting the timestamp when a command completes. Cc: stable@kernel.org #2.6.39, #3.0.0 #3.1.0 Signed-off-by: Johannes Berg SIgned-off-by: Wey-Yi Guy Signed-off-by: John W.
