Subject[PATCH 12/30] net: netrom: Add missing annotation for nr_neigh_start()
Date
Sparse reports a warning at nr_neigh_start()
warning: context imbalance in nr_neigh_start() - wrong count at exit
The root cause is the missing annotation at nr_neigh_start()
Add the missing __acquires(&nr_neigh_list_lock) annotation
