Subject: [PATCH v9 12/24] x86/sev: Make snp_issue_guest_request() static
Date: Fri, 31 May 2024 10:00:26 +0530 [thread overview]
Message-ID: <20240531043038.3370793-13-nikunj@amd.com> (raw)
In-Reply-To: <20240531043038.3370793-1-nikunj@amd.com>
As there is no external caller for snp_issue_guest_request() anymore,
make it static and drop the prototype from the header.
No functional change.
