I hate the fact that it is taking so long to get done with this. But can't you
just check machine compatibility instead of this complicated setup to check OPP
node ? Like:

if (!of_device_is_compatible("qcom,apq8096") &&
!of_device_is_compatible("qcom,msm8996"))
return;

And please see if you can add an entry in MAINTAINERS and add your working email
id there.
