of_get_required_opp_performance_state() returns 0 on errors currently and a positive performance state otherwise. Since 0 is a valid performance state (representing off), it would be better if this routine returns negative values on error. That will also make it behave similar to dev_pm_opp_xlate_performance_state(), which also returns performance states and returns negative values on error. Change the return type of the function to "int" in order to return negative values. This doesn't have any users for now and so no other part of the kernel will be impacted with this change.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
