Hi Kai-Heng,
I am facing the same bug. Unfortunately your patch does not seem to fix the bug for me, the nvidia GPU stays constantly active. Only if I unbind the snd-hda-intel module for this PCI device that the nvidia GPU will eventually go to sleep.
Nevermind, I'm stupid. I think I just didn't have the PM mode set to "auto", because I tried again and it works now. Ignore my email.
If you (or anybody) does a v3, please Cc me.
Cheers, -Paul

Similar to commit 9479e75fca37 ("ALSA: hda: Keep the controller initialization even if no codecs found"), when codec probe fails, it doesn't enable runtime suspend, and can prevent graphics card from getting powered down: [ 4.280991] snd_hda_intel 0000:01:00.1: no codecs initialized
$ cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status active
So mark there's no codec and continue probing to let runtime PM to work.
