From: Johannes Berg Date: Mon, 5 Mar 2012 19:24:28 +0000 (-0800) Subject: iwlwifi: make EXIT_PENDING depend on mac80211 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5c40d8603d8ed03aa851d20ad8a9155fc79a1b07;p=openwrt%2Fstaging%2Fblogic.git 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.
