[PATCH] Revert "PCI: Enable NVIDIA HDA controllers"
...is e0547c81bfcf ("PCI: Reset Lenovo ThinkPad P50 nvgpu at boot
if necessary").
Please describe in more detail how the GPU's PCI function stops working.
Does it respond with "all ones" when accessing MMIO?
Do MMIO accesses cause the system to hang?
Could you provide lspci -vvxx output for the GPU and its associated
HDA controller with and without b516ea586d71?
Does this machine have external display connectors via which audio
can be streamed?

[PATCH] Revert "PCI: Enable NVIDIA HDA controllers"
This reverts commit b516ea586d717472178e6ef1c152e85608b0ce32.
While this fixes audio for a number of users, this commit has the
sideaffect of breaking the BIOS workaround that's required to make the
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.
