vgaarb: Stub vga_set_legacy_decoding()
vga_set_legacy_decoding() is defined in drivers/gpu/vga/vgaarb.c, which is only compiled with CONFIG_VGA_ARB. A caller would therefore get an undefined symbol if the VGA arbiter is not enabled. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Acked-by: Dave Airlie <airlied@redhat.com>
