[PATCH 00/10] Set up generic fbdev after registering device

[Thomas Zimmermann <tzimmermann@suse.de>]

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.
