From f094d881954982b559e98e90aca1bf6f45141420 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 29 Aug 2016 10:27:52 +0200 Subject: [PATCH] drm: Remove drm_mode_object->atomic_count It's only used in drm_mode_object_get_properties, and we can compute it there directly with a bit of code shuffling.
