This reliably produces null pointer dereference errors in
	__platform_driver_register called from rockchip_drm_init
on at least rk3036 and rk3288 (probably more) when applied on top of 
Linus' tree from today. Log attached and Rockchip drm compiled as module.

I'm currently dug into other areas, so hadn't have time to investigate further 
yet.
