Subject: cfg80211: pmsr: fix MAC address setting
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0acd99282bef617fdbc4dff29359fe8160f00846;p=openwrt%2Fstaging%2Fblogic.git

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.

Fixes: 9bb7e0f24e7e ("cfg80211: add peer measurement with FTM initiator API")
