Subject: [PATCH 4.19 328/421] scsi: lpfc: Fix crash when lpfc_sli4_hba_setup() fails to initialize the SGLs
From: James Smart <jsmart2021@...il.com>
[ Upstream commit 5aa615d195f1e142c662cb2253f057c9baec7531 ]
The driver is encountering a crash in lpfc_free_iocb_list() while
performing initial attachment.
Code review found this to be an errant failure path that was taken, jumping
to a tag that then referenced structures that were uninitialized.
Fix the failure path.
