This reverts commit 145eed48de278007f646b908fd70ac59d24ed81a.

Zeno Davatz reported that 145eed48de27 ("fbdev: Remove conflicting devices
on PCI bus") caused a console hang.  The machine was actually still usable
via ssh, etc., but there was no activity on the console.

Reverting 145eed48de27 for the nvidiafb on that system fixed the problem.

Revert 145eed48de27 ("fbdev: Remove conflicting devices on PCI bus") since
we don't know what caused the problem.

The original patch is related to drm, and came in through the drm-misc
tree, so please drm folks, take such revert through the drm-misc
tree (if the patch is ok) as well.

Thanks,
Helge

Why is the user using nvidiafb?

This exposes a bug in nvidiafb, The user shouldn't even be using the
driver, it does nothing on their hardware, but it does a lot of things
before it binds.

nvidiafb should be fixed to probe the hw to see if it supports it
before it removes the framebuffer. I don't think reverting this patch
in full is the right answer, though we could revert the core bits and
allow nvidia fb to limp along until it's fixed or shot.

Dave.
