[PATCH] [SCSI] bfa: check if port is non NULL before dereferencing

2015-08-17 Thread Johannes Thumshirn
In bfa_fcs_lport_get_rport_max_speed() check if port is non NULL before
dereferencing it's child port->fcs->bfa to trl_enabled.

NB: I'm not entirely sure if port can even be NULL, so the check for NULL might
be useless as well.
