There are two types of duplicate OPPs that get different behavior from the core: A) An earlier OPP is marked 'available' and has same freq/voltages as the new one. B) An earlier OPP with same frequency, but is marked 'unavailable' OR doesn't have same voltages as the new one. The OPP core returns 0 for the first one, but -EEXIST for the second. While the OPP core returns 0 for the first case, its callers don't free the newly allocated OPP structure which isn't used anymore. Fix that by returning -EBUSY instead of 0, but make the callers return 0 eventually. As this isn't a critical fix, its not getting marked for stable kernel.

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.
