Unable to unselect VGA_ARB (VGA Arbitration)

[Paul Menzel <pmenzel@xxxxxxxxxxxxx>]

Dear Linux folks,


I am using Linux 5.16, and I am unable to unset `VGA_ARB` in Kconfig 
(`make menuconfig`). I have an Asus F2A85-M PRO with an AMD A6-6400K APU 
(integrated Radeon graphics device), so no legacy stuff.

From `drivers/gpu/vga/Kconfig`:

```
config VGA_ARB
        bool "VGA Arbitration" if EXPERT
        default y
        depends on (PCI && !S390)
        help
          […]

config VGA_ARB_MAX_GPUS
        int "Maximum number of GPUs"
        default 16
        depends on VGA_ARB
        help
          […]

config VGA_SWITCHEROO
        bool "Laptop Hybrid Graphics - GPU switching support"
        depends on X86
        depends on ACPI
        depends on PCI
        depends on (FRAMEBUFFER_CONSOLE=n || FB=y)
        select VGA_ARB
        help
          […]
```

But in `make menuconfig` I am unable to unselect it.

    -*- VGA Arbitration

and the help says:

    Symbol: VGA_ARB [=y]
    Type  : bool
      Depends on: HAS_IOMEM [=y] && PCI [=y] && !S390
      Visible if: HAS_IOMEM [=y] && PCI [=y] && !S390 && EXPERT [=n]
      Location:
        Main menu
         -> Device Drivers
           -> Graphics support
    Selected by [n]:
      - VGA_SWITCHEROO [=n] && HAS_IOMEM [=y] && X86 [=y] && ACPI [=y] 
&& PCI [=y] && (!FRAMEBUFFER_CONSOLE [=y] || FB [=y]=y)

So, VGA_SWITCHEROO is not set, and, therefore, as `Selected by [n]:` 
suggests, I thought I’d be able to deselect it.

It’d be great if you could help me out.


Kind regards,

Paul
