From b68710a8094fdffe8dd4f7a82c82649f479bb453 Mon Sep 17 00:00:00 2001 From: Quinn Tran qutran@marvell.com Date: Wed, 7 Jun 2023 17:08:40 +0530 Subject: [PATCH] scsi: qla2xxx: Fix buffer overrun

Klocwork warning: Buffer Overflow - Array Index Out of Bounds

Driver uses fc_els_flogi to calculate size of buffer. The actual buffer is nested inside of fc_els_flogi which is smaller.

Replace structure name to allow proper size calculation.
