[Intel-gfx] [PATCH 1/2] drm: call pci_disable_device on module onload

[Daniel Vetter]

Otherwise we'll nicely leak this reference counter. Now thanks to the
awesome layering in the drm core, the enable call is done by the pci
boilerplate in drm_pci.c. But the disable can't be done without adding
yet another neat indirection layer just for that.

So take the simple way and sprinkle pci_disable_device over all pci
modesetting drivers.

Also don't forget these dear old legacy drivers, prinkle the
pci_disable_device call in drm_pci_exit to cover these, too.
