commit b4bdc4fbf8d0 ("soc: sunxi: Deal with the MBUS DMA offsets in a central place") added a platform device notifier that sets the DMA offset for all of the display engine frontend and backend devices.
The code applying the offset to DMA buffer physical addresses was then removed from the backend driver in commit 756668ba682e ("drm/sun4i: backend: Remove the MBUS quirks"), but the code subtracting PHYS_OFFSET was left in the frontend driver.

Applied to drm/drm-misc (drm-misc-fixes).
Thanks! Maxime
