Subject: [XEN PATCH 4/5] x86/hvm: dom0: use helper to get sizeof struct field
Date: Thu, 14 Dec 2023 12:44:09 +0100	[thread overview]
Message-ID: <17b01f14b89a5dba6935bbd8019ddf431d595890.1702553835.git.nicola.vetrini@bugseng.com> (raw)
In-Reply-To: <cover.1702553835.git.nicola.vetrini@bugseng.com>

Use of the proper helper macro also resolves a violation
of MISRA C Rule 11.9.
No functional change.
