From: Max Krummenacher <max.oss...@gmail.com>
With kernel 5.16 some structs in pmu-events do get a const qualifier, some
a static const storage class and qualifier.
The current sort-pmuevents cannot cope with that and drops all struct
arrays with such additional elements. This then leads to compiler errors.
Allow '^struct', '^const struct', '^static struct', '^static const struct'.
