I think that patch was held for a moment, it appears on dri-devel archive now: https://lists.freedesktop.org/archives/dri-devel/2020-November/287958.html I did receive an email from 'linux-arm-kernel' that says the msg body of that patch is too big(> 100KB), thus being held for moderator's review(I hope it pass now). Maybe, dri-devel did sth similar.
