Event delete removes an event from the event list, but common code invokes the PMU's enable function later on. This happens in event_sched_out() and leads to the following call sequence: event_sched_out() +--> cpumsf_pmu_del() +--> cpumsf_pmu_enable() In cpumsf_pmu_enable() return immediately when the event is not active. Also remove an unneeded if clause. That if() statement is only reached when flag PMU_F_IN_USE has been set in cpumsf_pmu_add(). And this function also sets cpuhw->event to a valid value. Remove WARN_ON_ONCE() statement which never triggered.

README
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 reStructuredText 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.
