This is a simple 1:1 conversion.
But some cases - I checked ast_set_dp501_video_output() =>
ast_write_cmd(), ast_write_data()
could have been fixed by passing ast_private * rather than drm_device *.
And then no upcasting was needed.
That a more involved approach - but wanted to point it out.
Maybe for another day..

The ast variable in ast_crtc_helperatomic_check() is unused,
s/ast_crtc_helperatomic_check/ast_crtc_helper_atomic_check/
