Hi,
I was not aware the faux-device was merged, as it is a new feature, I
expected it to reach drm-misc-next on 6.15-rc1.
I plan to merge [1] today/tomorrow (well tested with platform_device),
and then I will submit an updated version of this patch (only trivial
conflicts, but never tested with multiple VKMS devices).
