[PATCH 12/30] net: netrom: Add missing annotation for nr_neigh_start()

From: Jules Irenge <hidden>
Date: 2020-02-23 23:19:25
Also in: linux-hams, lkml
Subsystem: networking [general], the rest · Maintainers: "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

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
