OK. That means there's something else still that I'm missing :(

That does seem like it would work, but definitely not the way that I'd do it.
I'd do more like

cd linux
git checkout 8e9e3d2deacc460fbb8a4691140318f6e85e6891
git checkout drivers/gpu/drm/nouveau (this should remove any local changes you
have in that dir on tracked files)
patch -p1 < hdmi-1.patch
patch -p1 < hdminva3.patch
patch -p1 < hdminva3-3.patch

> # Build, reboot, test:
> cat /proc/asound/card1/eld#3.0                  # Good, Bad?
> aplay -D plughw:1,9 test.wav                    # HDMI sound?
