Boris Brezillon 36e9d08b58 drm/cirrus: Fix NULL pointer dereference when registering the fbdev ... cirrus_modeset_init() is initializing/registering the emulated fbdev and, since commit c61b93fe51 ("drm/atomic: Fix remaining places where !funcs->best_encoder is valid"), DRM internals can access/test some of the fields in mode_config->funcs as part of the fbdev registration process. Make sure dev->mode_config.funcs is properly set to avoid dereferencing a NULL pointer. Reported-by: Mike Marshall <hubcap@omnibond.com> Reported-by: Eric W.
