From 0cf746d8b052d3f34f386f2d59f2be8bc8fa2f08 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 3 Aug 2020 11:02:10 +0200 Subject: [PATCH] mac80211: fix misplaced while instead of if commit 5981fe5b0529ba25d95f37d7faa434183ad618c5 upstream. 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.
