[PATCH] drm: Some ocd in drm_file.c

[Chris Wilson]

Quoting Daniel Vetter (2019-05-02 14:56:03)
> Move the open helper around to avoid the forward decl, and give
> drm_setup a drm_legacy_ prefix since it's all legacy stuff in there.
> 
> v2: Move drm_legacy_setup into drm_legacy_misc.c (Chris). The
> counterpart in the form of drm_legacy_dev_reinit is there already too,
> plus it fits perfectly into Dave's work of making DRIVER_LEGACY code
> compile-time optional.
