Subject: [PATCH 08/11] lpfc: Fix crash when lpfc_sli4_hba_setup fails to initialize the SGLs
Date: Fri, 14 May 2021 12:55:56 -0700	[thread overview]
Message-ID: <20210514195559.119853-9-jsmart2021@gmail.com> (raw)
In-Reply-To: <20210514195559.119853-1-jsmart2021@gmail.com>

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.
