Subject: mac80211: notify channel switch at the end of ieee80211_chswitch_post_beacon()
From: Luciano Coelho <luciano.coelho@xxxxxxxxx>
commit 688b1ecfb9ed0484754d2653386e3c44c58ede5c upstream.
The call to cfg80211_ch_switch_notify() should be at the end of the
ieee80211_chswitch_post_beacon() function, because it should only be
sent if everything succeeded.
Fixes: d04b5ac9e70b ("cfg80211/mac80211: allow any interface to send channel switch notifications")
