Subject: [PATCH] scsi: lpfc: remove an unnecessary NULL check
Git-commit: 26c724a690a1cd10575365da90b5b4040278a6c5
Patch-Mainline: v4.20-rc1
References: bsc#1121317, bsc#1123236
Smatch complains about this code:
drivers/scsi/lpfc/lpfc_scsi.c:1053 lpfc_get_scsi_buf_s4()
warn: variable dereferenced before check 'lpfc_cmd' (see line 1039)
Fortunately the NULL check isn't required so I have removed it.
