[PATCH 8/8] staging: unisys: visornic: handle error return from device registration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no code to handle an error return in visornic, when it tries to
register with visorbus. This patch handles an error return from
visorbus_register_visor_driver() by dropping out of initialization.
