This was never noticed since DP_REMOTE_DPCD_READ is currently not

Sorry, this v2 patch series is a bit messy: my git-send-email failed at patch 3
for some reason, so I posted patches 3-5 manually, but I forgot to add 'v2' to
the
subject of patch 4/5 and for some reason patch 3 now appeared twice. The
contents
of the patches is correct, though :-)

If you maintain one of these drivers and you want to merge it for v5.4
yourself, then please do so and let me know. If you prefer I commit it

gv100_hdmi_ctrl() writes vendor_infoframe.subpack0_high to 0x6f0110, and
then overwrites it with 0. Just drop the overwrite with 0, that's clearly
a mistake.
Because of this issue the HDMI VIC is 0 instead of 1 in the HDMI Vendor
InfoFrame when transmitting 4kp30.
