[ Upstream commitc7c1b9e1d5] Rework fbdev probing to support fbdev_probe in struct drm_driver and reimplement the old fb_probe callback on top of it. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. This change allows the common fbdev client to run on top of TTM- based DRM drivers.
