[PATCH v3 05/17] perf jevents: Remove the type/version variables

From: Ian Rogers
Date: Fri Jul 29 2022 - 03:44:37 EST


pmu_events_map has a type variable that is always initialized to "core"
and a version variable that is never read. Remove these from the API as
it is straightforward to add them back when necessary.
