Acked-by: Tim Gardner <tim.gardner@canonical.com> The Focal backport looks good. Clean cherry-picks otherwise.

Thanks, Kleber
BugLink: https://bugs.launchpad.net/bugs/1939052 In the V2, added one more patch to fix the 1st patch. [Impact] The speaker on a coule of Lenovo laptops can't output sound, need to do special initialization. [Fix] Backport a upstream patch, the patch will initialize the speaker amplifier with special verbs. [Test] Booting the patched kernel, output the sound to speaker, could heaer the sound. [Where problems could occur] The patch set the quirk to some lenovo machines with subsystem id, there is no regression risk for other machines.
