Subject[PATCH 5.10 051/101] mac80211: reset profile_periodicity/ema_ap
Date
From: Johannes Berg <johannes.berg@intel.com>

[ 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.
