wl12xx: remove unneeded locking
With the scan callback now being callable from any context, these unlocks/locks can go away. This makes the code easier to understand, since callers of these functions must no longer be aware that the mutex may be dropped. As Stanislaw is working on iwlwifi scanning, I didn't change it to take advantage of the new mac80211 semantics. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
