Subject: [RFC v1 1/4] ACPI: x86: s2idle: Export symbol for fetching constraints for module use
Date: Mon, 9 Oct 2023 17:56:50 -0500 [thread overview]
Message-ID: <20231009225653.36030-2-mario.limonciello@amd.com> (raw)
In-Reply-To: <20231009225653.36030-1-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.
