wanrouter: fix sparse warnings: context imbalance
Impact: Attribute functions with __acquires(...) resp. __releases(...). Fix this sparse warnings: net/wanrouter/wanproc.c:82:13: warning: context imbalance in 'r_start' - wrong count at exit net/wanrouter/wanproc.c:103:13: warning: context imbalance in 'r_stop' - unexpected unlock net/wanrouter/wanmain.c:765:13: warning: context imbalance in 'lock_adapter_irq' - wrong count at exit net/wanrouter/wanmain.c:771:13: warning: context imbalance in 'unlock_adapter_irq' - unexpected unlock Signed-off-by: Hannes Eder <hannes@hanneseder.net> Signed-off-by: David S.
