Subject: [PATCH] mac80211: reset profile_periodicity/ema_ap
Git-commit: bbc6f03ff26e7b71d6135a7b78ce40e7dee3d86a
Patch-mainline: v5.13-rc7
References: git-fixes

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.
