Subject[PATCH AUTOSEL 4.18 018/131] scsi: qla2xxx: Silent erroneous message
Date
From: Quinn Tran <quinn.tran@cavium.com>

[ Upstream commit 3f915271b12e11183c606bed1c3dfff0983662d3 ]

Driver uses shadow pointer instead of Mirror pointer for firmware dump
collection. Skip those entries for Mirror pointers for Request/Response
queue from firmware dump template reading.

Following messages are printed in log messages:

qla27xx_fwdt_entry_t268: unknown buffer 4
qla27xx_fwdt_entry_t268: unknown buffer 5

This patch fixes these error messages by adding skip_entry() to not read
them from template.
