[PATCH v3 3/5] drm/tinydrm: Use struct drm_rect
Noralf Trønnes
noralf at tronnes.org
Tue Jan 15 04:36:41 UTC 2019
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.
