Will fix that.

Yes, I wanted to do that, but there is no reliable way of check that; there is
no ofnode before module load, and there won't be any PAPR specific DT entries if
the platform is not Power.
I also test the 'ndtest' module on x86 with NDCTL_TEST_FAMILY environment
variable. I can let the default be nfit_test (NVDIMM_FAMILY_INTEL) and only load
PAPR module when the environment variable is set. Thoughts?
Thanks,
