4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Paul seanpaul@chromium.org
[ Upstream commit 96fc56a775c1e44c0e3c0119f2cd3d77431c4569 ]
The atomic_check is a bit too aggressive with respect to planes which leave the active area. This caused a bunch of log spew when the cursor got to the edge of the screen and stopped it from going all the way.
This patch removes the conservative bounds checks from atomic and clips the dst rect such that we properly display planes which go off the screen.
Changes in v2: - Apply the clip to src as well (taking into account scaling) Changes in v3: - Use drm_atomic_helper_check_plane_state() to clip src/dst
