[PATCH v3 1/3] PM / OPP: Expose _of_get_opp_desc_node as dev_pm_opp API

[kbuild test robot]

Hi Dave,

[auto build test ERROR on robh/for-next]
[also build test ERROR on v4.9-rc2]
[cannot apply to pm/linux-next next-20161027]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
