The commit can't be cherry-picked by itself onto v4.13, it was part of
a larger series. It's best to use a stock v4.17 kernel.
Note, a fix went into Linus' tree yesterday, commit 57cb54e53bdd
("ALSA: hda - Force to link down at runtime suspend on ATI/AMD HDMI").
Not sure if it's needed on your machine.
Thanks,
