scsi: lpfc: Fix oops when NVME Target is discovered in a nonNVME environment
lpfc oops when it discovers a NVME target but is configured for SCSI only operation. Oops is in lpfc_nvme_register_port+0x33/0x300. The localport is not valid so it should not have been referenced. Added validity check for localport Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Martin K.
