Subject: [PATCH v17 1/4] ACPI: x86: s2idle: Export symbol for fetching constraints for module use
Date: Wed, 6 Sep 2023 13:43:51 -0500 [thread overview]
Message-ID: <20230906184354.45846-2-mario.limonciello@amd.com> (raw)
In-Reply-To: <20230906184354.45846-1-mario.limonciello@amd.com>
The amd-pmc driver will be fetching constraints to make decisions at
suspend time. This driver can be compiled as a module, so export the
symbol for when it is a module.
