(In reply to Jean-Sébastien Pédron from comment #16)

That patch won't work as nvidia is native PCI code and never calls
pci_register_driver.
So no need to test it.

The patch I emailed to Adrian and Austin adds the pdrv to the
linux_pci_attach_device() with isdrm already set but I haven't heard back.  
That said, that would change the code path in this case and do set things
differently to what is currently done, so I am not sure if that's where the
change of value comes from.  Are you thinking that it is currently not properly
set and previously the partial native PCI calls in drm concealed that?

I'll attach both the nvidia-drm patch and a debugging patch I made (but my
amdgpu still panics so I cannot test) later today, once I can get back to that
machine.
