Bjorn Helgaas 505a1b5717 vgaarb: Factor out EFI and fallback default device selection ... The default VGA device is normally set in vga_arbiter_add_pci_device() when we call it for the first enabled device that can be accessed with the legacy VGA resources ([mem 0xa0000-0xbffff], etc.) That default device can be overridden by an EFI device that owns the boot framebuffer. As a fallback, we can also select a VGA device that can't be accessed via legacy VGA resources, or a VGA device that isn't even enabled. Factor out this EFI and fallback selection from vga_arb_device_init() into a separate vga_arb_select_default_device() function. This doesn't change any behavior, but it untangles the "bridge control possible" checking and messages from the default device selection.
