The drm core shouldn't depend upon any helpers, and we make sure this doesn't accidentally happen by moving them into the helper-only drm_kms_helper.ko module.

Are there any KMS drivers that don't 'select DRM_KMS_HELPER' in their Kconfig today? From a quick grep + cscope it looks like radeon and vmwgfx don't select the helper library.
Since drm_crtc_init() is part of the helper library now (since it creates a helper-created primary plane), I think those drivers either need to select the helper in their Kconfig to get a proper build, or they need to be updated to provide their own primary planes and call drm_crtc_init_with_planes(), right?
Radeon definitely uses the crtc helpers, so should have the dependency somewhere. vmwgfx might indeed be broken now a bit. I'll wait for the 0-day kernel test build farm to confirm that ;-) -Daniel
