It definitely needs to be fixed, and I'd suggest its early enough in the
-rc cycle (which hasn't begun yet) to simply fix drm_of_component_probe()
to take two compare functions.

I'd also suggest at this point another change: please rename it to
drm_of_kms_component_probe() since this is only a generic case for KMS
drivers.  GPU DRM drivers need something different.
