From ff6bf89717b0dc7b8dd0934d1c065f29069831e7 Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 12 Mar 2019 16:30:04 -0700 Subject: [PATCH] scsi: lpfc: Resolve inconsistent check of hdwq in lpfc_scsi_cmd_iocb_cmpl A prior patch which added support for non-uniform allocation of MSIX vectors now causes a smatch complaint: drivers/scsi/lpfc/lpfc_scsi.c:3674 lpfc_scsi_cmd_iocb_cmpl() error: we previously assumed 'phba->sli4_hba.hdwq' could be null (see line 3667) Resolve by removing the unnecessary check for a NULL hdwq table.
