From 6ab10b76ff6252bd9be0849c40f5865e39a29961 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 12 Aug 2016 22:48:45 +0200 Subject: [PATCH] drm/kms: Nuke dirty_info property It was added way back together with the dirty_fb ioctl, but neither generic xfree86-modesetting nor the vmware driver use it. Everyone is supposed to just unconditionally call the dirtyfb when they do frontbuffer rendering. And since unused uabi is bad uabi (there's reasons we require open source userspace for everything) let's nuke this.
