It compiles cleanly and works: the driver probes, finds the panel on the coretile CLCD, registers ("Initialized pl111 on minor 0") and the boot goes through all of device init without any splats. One observation: with the alpha formats still in the tables, registration prints the "[PLANE:35:plane-0] pixel format with alpha exposed but blend mode not setup" message once (drm_warn, non-fatal since 271e90eb converted the validation away from WARN). I also stacked my format removal patch on top of the rework: it applies cleanly despite the renames, and the combined boot is fully silent. So the two changes are orthogonal and can merge in either order. Tested-by: Roshan Kumar # Ze Huang's patch, QEMU vexpre= ss
