It is possible that a failure can occur during the scheduling of a pinned event. The initial portion of perf_event_read_local() contains the various error checks an event should pass before it can be considered valid. Ensure that the potential scheduling failure of a pinned event is checked for and have a credible error.

The Linux kernel user's and administrator's guide
=================================================
The following is a collection of user-oriented documents that have been
added to the kernel over time. There is, as yet, little overall order or
organization here — this material was not written to be a single, coherent
document! With luck things will improve quickly over time.
This initial section contains overall information, including the README
file describing the kernel as a whole, documentation on kernel parameters,
etc.

This section describes CPU vulnerabilities and provides an overview of the
possible mitigations along with guidance for selecting mitigations if they
are configurable at compile, boot or run time.
