From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit f7e60032c6618dfd643c7210d5cba2789e2de2e2 upstream.
This should use wiphy_lock() now instead of requiring the
RTNL, since __cfg80211_leave() via cfg80211_leave() is now
requiring that lock to be held.
Fixes: a05829a7222e ("cfg80211: avoid holding the RTNL when calling the driver")
