The series looks good to me:

Acked-by: Hans de Goede <hdegoede@redhat.com>

For the series.

Not sure if this is really 5.17 material this late in the cycle though,
but lets wait and see what Bjorn and Lee have to say (patch 8/8 still
needs an ack from Lee).

I'm fine with taking this upstream through the pdx86 tree, please
prepare a pull-req for everyone involved with an immutable branch
pushed to pdx86/platform-drivers-x86.git/
based on 5.16-rc1 (if everyone is happy with merging this for 5.17) or
based on 5.17-rc1 once that is out.

Regards,

Hans
