Subject: Re: [PATCH v3 3/6] LoongArch/PCI: Remove vga default device override

> pci_fixup_vgadev() forces the VGA default device to a non-Loongson VGA
> device whenever a Loongson display controller is present.  This was
> added to prefer a discrete graphics card as the default boot device, but
> it makes vga_default_device() inconsistent with the firmware boot
> display: the firmware framebuffer lives on the integrated controller,
> while the override points the default at a discrete card (or leaves it
> unset when there is no discrete card).
> 
> The fixup runs from pci_bus_add_device(), i.e. after the VGA arbiter has
> already selected the default device through the firmware framebuffer, so
> it overrides that choice.  Drop it so vga_default_device() consistently
> reflects the boot display.
