[PATCH] Detaching fbcon: remove calls to pci_disable_device()
Detaching fbcon allows individual drivers to be unloaded. However several drivers call pci_disable_device() upon exit. This function will disable the BAR's which will kill VGA text mode and/or affect X/DRM. To prevent this, remove calls to pci_disable_device() from several drivers.
