Subject: mac80211: fix warning in ieee80211_probe_client
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b4487c2d0edaf1332d7a9f11b5661044955ef5e2;p=linux-beck.git

mac80211: fix warning in ieee80211_probe_client

The warning is spurious -- if !sta we always exit without using the
unassigned qos variable, and if we do find the sta we assign it.
