Generic fbdev emulation is a DRM client. If possible, it should behave like userspace clients. Therefore it should not run before the driver registered the new DRM device. If the setup function fails, the driver should not report an error. This is a follow-up patchset to the discussion at [1]. I went through all calls to drm_fbdev_generic_setup(), moved them to the final operation of their driver's probe function, and removed the return value. Built-tested on x86-64, aarch64 and arm.
