commit 7c174f305cbee6bdba5018aae02b84369e7ab995 upstream. The find_arch_event() returns a "unsigned int" value, which is used by the pmc_reprogram_counter() to program a PERF_TYPE_HARDWARE type perf_event. The returned value is actually the kernel defined generic perf_hw_id, let's rename it to pmc_perf_hw_id() with simpler incoming parameters for better self-explanation.

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.
