Subject: [PATCH 29/32] hwmon: Stop using 32-bit MSR interfaces
Date: Mon, 29 Jun 2026 08:05:20 +0200 [thread overview]
Message-ID: <20260629060526.3638272-30-jgross@suse.com> (raw)
In-Reply-To: <20260629060526.3638272-1-jgross@suse.com>
The 32-bit MSR interface rdmsr() is planned to be removed. Use the
related 64-bit variant instead.
