Yeah, agreed that there's no reason but others drivers already add the
_helper prefix for struct drm_*_helper_funcs callbacks, and I did that
in this driver as well to follow (what appears to be?) a convention.

So I've to that now for the struct drm_crtc_helper_funcs handlers to be
consistent with the rest of the driver, e.g for plane:

static const struct drm_plane_helper_funcs ssd130x_primary_plane_helper_funcs = {
	DRM_GEM_SHADOW_PLANE_HELPER_FUNCS,
	.atomic_check = ssd130x_primary_plane_helper_atomic_check,
	.atomic_update = ssd130x_primary_plane_helper_atomic_update,
	.atomic_disable = ssd130x_primary_plane_helper_atomic_disable,
};

static const struct drm_plane_funcs ssd130x_primary_plane_funcs = {
	.update_plane = drm_atomic_helper_update_plane,
	.disable_plane = drm_atomic_helper_disable_plane,
	.reset = ssd130x_primary_plane_reset,
	.atomic_duplicate_state = ssd130x_primary_plane_duplicate_state,
	.atomic_destroy_state = ssd130x_primary_plane_destroy_state,
	.destroy = drm_plane_cleanup,
};
