mac80211_hwsim: avoid NULL access There's a race condition -- started can be set to true before channel is set due to the way mac80211 callbacks currently work (->start should probably pass the channel we would like to have initially). For now simply add a check to hwsim to avoid dereferencing the NULL channel pointer. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
