From b051b3459bbae907ef068bcd8b62f73f09ea5016 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Noralf=20Tr=C3=B8nnes?= Date: Tue, 15 Jan 2019 05:36:41 +0100 Subject: [PATCH] drm/tinydrm: Use struct drm_rect MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This prepares for the switch to drm_atomic_helper_dirtyfb() in the next patch. The damage helper returns a drm_rect so switch to that everywhere including using a pointer in the dirty functions. This is a non-functional change except for the debug print which looks a bit different.
