Subject: [PATCH v2 0/2] Fix Optimus when GPU has no sound

See the commit descriptions.

As agreed in the previous discussion [1], this series adds the
non-functional NVIDIA HDA controller on Lenovo IdeaPad Z570 to the
denylist, and includes the runtime PM workaround from v1, which now
prints a warning to dmesg asking the user to add the device to the
denylist if it's affected and not already there.
