Subject: [PATCH v4 2/2] i8042: Use new forcenorestore quirk to replace old buggy quirk combination
Date: Thu,  4 Jan 2024 19:31:18 +0100

The old quirk combination sometimes cause a laggy keyboard after boot. With
the new quirk the initial issue of an unresponsive keyboard after s3 resume
is also fixed, but it doesn't have the negative side effect of the
sometimes laggy keyboard.
