The temporary pmu assignment in event_init is unnecessary. The assignment was introduced by commit8113070d66("perf_events: Add fast-path to the rescheduling code"). At that time, event->pmu is not assigned yet when initializing an event. The assignment is required. However, from commit7e5b2a01d2("perf: provide PMU when initing events"), the event->pmu is provided before event_init is invoked. The temporary pmu assignment in event_init should be removed.

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.
