[PATCH 0/3] agp/amd64: Remove support for probing unlisted PCI devices

Hi all,

As discussed in this thread:

https://lore.kernel.org/dri-devel/b29e7fbfc6d146f947603d0ebaef44cbd2f0d754.1751468802.git.lukas@wunner.de/

The amd64_agp driver's support for trying to probe unsupported devices does
not make sense anymore given that no new AGP devices have been produced for
a while now.

This patch series disabled the probing of unsupported devices in 2 steps
(for easier reverting and/or for applying one step at a time) first default
it to off and then completely remove it.

The first patch is a resend of Lukas' patch for 6.16-rc# to fix
the bootsplash regression caused by the probing of unsupported devices

I've included this patch so that the series applies cleanly, this means
that drm-misc-fixes (once it lands there) will needs to be backmerged
for the last patch to apply.

Regards,

Hans
