Subject: Re: [PATCH v7 12/13] media: verisilicon: Enable AV1 decoder on rk3588

Nicolas,

Can you review this patch? This is the only one without a Reviewed-by
from you. Once I have that, then I can make a PR.

I'll do a test build with sparse/smatch tests as well today to check that
there are no new warnings etc. introduced.

Regards,

	Hans
