Subject: [PATCH] scsi: lpfc: Remove set-but-not-used variables
References: bsc#1136217,jsc#SLE-4722
Git-commit: b27cbd5549509397c6e85b8aed1d9e95538c919e
Patch-mainline: v5.2-rc1
This patch does not change any functionality but avoids that the compiler
complains about set-but-not-used variables when building with W=1.
