Subject: [PATCH] scsi: qedf: missing kref_put in qedf_xmit()
Git-commit: 4262d35c32c652344b6784cad51ec5a0e2e5258b
Patch-Mainline: v5.2
References: bsc#1135542
qedf_xmit() calls fc_rport_lookup(), but discards the returned rdata
structure almost immediately without decreasing the refcount. This leads
to a refcount leak and the rdata never to be freed.
