Just had a crazy idea:
Would it make sense for the function(s) that takes the
driver_foo_funcs as an argument to cross-check for such mistakes?
Since many of the hooks are optional, one could check for the
'forbidden' combinations:
Atomic drivers should not have any legacy hooks set, while legacy ones
should not have any of the atomic ones.
Of course the idea is not restricted to the CRTC helpers -
drm_{crtc,encoder,connector,plane,mode_config}_{helper_,}funcs should
all be applicable.
Regards,
Emil
