Subject: [PATCH 4.19 060/205] scsi: qla2xxx: Fix NVMe Target discovery

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Quinn Tran <quinn.tran@...ium.com>

commit db186382af21e926e90df19499475f2552192b77 upstream.

This patch fixes issue when remoteport registers itself as both FCP and
FC-NVMe with the switch, driver will pick FC-NVMe personality as default when
scanning for targets.

Driver was using comaprative operator instead of bitwise operator to check for
fc4_type for both FCP and FC-NVME.
