Thanks a lot, Mario.


Is it possible to merge the PCI/VGA part as fast as possible, especially the

PATCH-0006 PCI/VGA: Introduce is_boot_device function callback to vga_client_register

As this patch is fundamental, it introduce no functional change, as long as the drm

driver side don't introduce a callback.

I'm not hurry, but drm driver-side's patch have a dependency on this patch,

I think it is better the PCI/VGA-side's patch got merge first.

At least for get the first four cleanup(0001 ~ 0004) patch merged first,

so that I don't have to send so much on the next version on one series.

Being exposed so far, there no obvious objection.

It saying that other people also want it got merged.

Bjorn, is this OK ?
