This mode_config_initialized is hilarious. I think (from looking at git
history and all) this started in radeon, back when kms was an add-on, and
radeon.ko still supported ums. Then it was dutifully copypasted into
cirrus, bochs, mgag200, hisilicon and also amdgpu.

Afaict none of these drivers need this (but I didn't bother to review
amdgpu and radeon fully). Would be nice little cleanup to follow up with.

Anyway, on your 3 patches here:
