Subject: [PATCH 2/4] scsi: lpfc: Return directly after a failed kzalloc() in lpfc_sli_read_link_ste()
Date: Thu, 28 Dec 2023 18:24:05 +0100	[thread overview]
Message-ID: <cef48477-8331-4d84-a3ee-8e6b2f6e34e8@web.de> (raw)
In-Reply-To: <48a127e8-ca4f-4fc4-81b7-226080fba720@web.de>

From: Markus Elfring <elfring@users.sourceforge.net>

The kfree() function was called in one case by
the lpfc_sli_read_link_ste() function during error handling
even if the passed variable contained a null pointer.
This issue was detected by using the Coccinelle software.

Thus return directly after a call of the function “kzalloc” failed
at the beginning.
