Subject: [PATCH 2/2] platform/x86/amd: pmf: Use meta + L for screen lock command
From: Mario Limonciello <mario.limonciello@....com>
In practice userspace software doesn't react to KEY_SCREENLOCK by default.
So any time that the PMF policies would suggest to lock the screen (for
example from an HPD sensor event) userspace isn't configured to do it.
However userspace is configured for meta + L as this is the default
in the PC ecosystem. Adjust the PMF driver to send meta + L.
