Subject: [PATCH] decnet: fix sparse warnings: context imbalance
Impact: Attribute functions with __acquires(...) resp. __releases(...).
Fix this sparse warnings:
net/decnet/dn_dev.c:1324:13: warning: context imbalance in 'dn_dev_seq_start' - wrong count at exit
net/decnet/dn_dev.c:1366:13: warning: context imbalance in 'dn_dev_seq_stop' - unexpected unlock
