From 5c40d8603d8ed03aa851d20ad8a9155fc79a1b07 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 5 Mar 2012 11:24:28 -0800 Subject: [PATCH] iwlwifi: make EXIT_PENDING depend on mac80211 There's no reason to set EXIT_PENDING when we start removing the module, as mac80211 will cleanly shut down the device in this case. Additionally, there's no point in rejecting commands to the device when we're cleaning up as that only leads to unwanted errors from mac80211 being printed, such as failed to remove key (...) from hardware (-16) Signed-off-by: Johannes Berg Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
