It is possible for dev_pm_opp_find_freq_exact() to return errors. It was all fine earlier as dev_pm_opp_get_voltage() had a check within it to check for invalid OPPs, but dev_pm_opp_put() doesn't have any similar checks and the callers need to make sure OPP is valid before calling them. Also update the later dev_warn_ratelimited() to not print the error message as the OPP is guaranteed to be valid now.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
