Some computations in intel_pstate_get_min_max() are not necessary and one of its two callers doesn't even use the full result. First off, the fixed-point value of cpu->max_perf represents a non-negative number between 0 and 1 inclusive and cpu->min_perf cannot be greater than cpu->max_perf. It is not necessary to check those conditions every time the numbers in question are used. Moreover, since intel_pstate_max_within_limits() only needs the upper boundary, it doesn't make sense to compute the lower one in there and returning min and max from intel_pstate_get_min_max() via pointers doesn't look particularly nice. For the above reasons, drop intel_pstate_get_min_max(), add a helper to get the base P-state for min/max computations and carry out them directly in the previous callers of intel_pstate_get_min_max().

README
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.
