Subject: [PATCH 1/6] coco/tdx: Rename MSR access helpers
Date: Tue,  6 May 2025 11:20:10 +0200	[thread overview]
Message-ID: <20250506092015.1849-2-jgross@suse.com> (raw)
In-Reply-To: <20250506092015.1849-1-jgross@suse.com>

In order to avoid a name clash with some general MSR access helpers
after a future MSR infrastructure rework, rename the TDX specific
helpers.
