Subject: [PATCH 5.13 10/24] qede: Fix memset corruption
Date: Mon,  6 Sep 2021 14:55:39 +0200	[thread overview]
Message-ID: <20210906125449.451044864@linuxfoundation.org> (raw)
In-Reply-To: <20210906125449.112564040@linuxfoundation.org>

From: Shai Malin <smalin@marvell.com>

[ Upstream commit e543468869e2532f5d7926e8f417782b48eca3dc ]

Thanks to Kees Cook who detected the problem of memset that starting
from not the first member, but sized for the whole struct.
The better change will be to remove the redundant memset and to clear
only the msix_cnt member.
