Hi Chun-Kuang,
These two series are independent, so my preference would be to apply
whichever series becomes ready first. There won't technically be a
merge conflict, but I think the ovl-adaptor component will fail to
initialize correctly once the first patch of this series lands,
because the ovl-adaptor patch series does not yet implement the
get_formats() interface. I can send a follow-up patch after the
ovl-adaptor series lands, or let Nancy know about the potential
runtime issue.
Regards,
Justin
