> All these issues should be resolved by passing in the
> modifier, and for that we switch to using the PRIME_2

> Tested with experimental radeonsi patches for modifiers

> patches to double-check it works without PRIME_2 support.

> v2:
>  Cache PRIME_2 support to avoid doing two calls every time on
>  libva drivers that do not support it.
>
> v3:
>  Remove prime2_vas usage.

I've pinged jkqxz, the maintainer, but to me it looks good,
and considering how long this has been on the ML, I'll
apply it alongside the Vulkan patches if he doesn't respond.
By the way, it mentions the author is Bas Nieuwenhuizen,
should I change the commit author when I apply?
