From 352b205a3bac6bb68f27228768a5c12294e650bf Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 4 Mar 2019 20:39:08 +0100 Subject: [PATCH] scsi: lpfc: fix unused variable warning The newly introduced 'cpu' variable is only used inside of an optional block, so we get a warning without CONFIG_SCSI_LPFC_DEBUG_FS: drivers/scsi/lpfc/lpfc_nvme.c: In function 'lpfc_nvme_io_cmd_wqe_cmpl': drivers/scsi/lpfc/lpfc_nvme.c:968:30: error: unused variable 'cpu' [-Werror=unused-variable] uint32_t code, status, idx, cpu; Move the declaration into the same block to avoid the warning.
