If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dffee9d13446cea7679b160471d097494e76df26 Author: Johannes Berg <johannes.berg@xxxxxxxxx> Date: Fri Jun 18 13:41:49 2021 +0300 mac80211: reset profile_periodicity/ema_ap [ Upstream commit bbc6f03ff26e7b71d6135a7b78ce40e7dee3d86a ] Apparently we never clear these values, so they'll remain set since the setting of them is conditional. Clear the values in the relevant other cases.
