Can you paste the link (or atleast the title) of the patches that you are referring to ? I might then have to rework on this.
I also don't see the ARM_AFBC modifier in upstream yet, is that still in-flight somewhere?
I realized that I was missing the ack on my first patch of the series (ie https://lists.freedesktop.org/archives/dri-devel/2018-June/180125.html) and the reason I believe is that I did not put the correct email addresses in "--to" for the drm_fourcc.h maintainers. I will resend the patch and wait for their ack.
