From 0acd99282bef617fdbc4dff29359fe8160f00846 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 6 Feb 2019 07:59:41 +0200 Subject: [PATCH] cfg80211: pmsr: fix MAC address setting When we *don't* have a MAC address attribute, we shouldn't try to use this - this was intended to copy the local MAC address instead, so fix it.
