Of course it was tested on Exynos as this is HW I work on. Linus Walleij has also reported in this thread that device links have different issue

response explains it in detail.
Indeed, it was detailed in commit d6a77ba0eb92d8ffa4b05a442fc20d0a9b11c4c4
AFAICT the problem was that struct drm_device does not contain a struct device itself, just a pointer struct device * ->dev to the bus device which is unorthodox: most other device type have a full struct device inside them and the bus device would rather be that device's parent.
I had this situation with struct gpio_chip for a long time but eventually fixed it, which proved immensely helpful.
