-Subject: [PATCH] mac80211: fix misplaced while instead of if
-
-This never was intended to be a 'while' loop, it should've
-just been an 'if' instead of 'while'. Fix this.
-
-I noticed this while applying another patch from Ben that
-intended to fix a busy loop at this spot.

-Cc: stable@vger.kernel.org
