OK fair enough.

So you can add my
Acked-by: Gregory CLEMENT <[email-masked]>

Moreover to keep biscetability  this patch should be merged after the
support in the driver. So the easier is to let merge it through the PCI
subsystem with the other patches from this series. I do not think there
will be any other changes in this file so there won't be any merge
conflicts.

Thanks,
