This is missing a reference to the commit introducing the P50 quirk,
which is e0547c81bfcf ("PCI: Reset Lenovo ThinkPad P50 nvgpu at boot
if necessary").

Could you provide lspci -vvxx output for...

[PATCH] Revert "PCI: Enable NVIDIA HDA controllers"
This reverts commit b516ea586d717472178e6ef1c152e85608b0ce32.

GPU on the nvidia P50 work, by causing the GPU's PCI device function to
stop working after it's been set to multifunction mode.
