+Subject: [PATCH] mac80211: fix broken AP mode handling of powersave clients
+
+Commit c68df2e7be0c ("mac80211: allow using AP_LINK_PS with
+mac80211-generated TIM IE") introduced a logic error, where
+__sta_info_recalc_tim turns into a no-op if local->ops->set_tim is not
+set. This prevents the beacon TIM bit from being set for all drivers
+that do not implement this op (almost all of them), thus thoroughly
+essential AP mode powersave functionality.
+

+Fixes: c68df2e7be0c ("mac80211: allow using AP_LINK_PS with mac80211-generated TIM IE")
