Not 100% sure if that is the right commit to reference because it didn't
touch pmu.y.

perf_pmu_lex is still used and there are plenty of references to it, but
maybe the extern declaration isn't needed anymore because it still
builds for me with this change.

I left it as:

perf pmu: Remove perf_pmu_lex() needless declaration

It builds without it, perhaps with some older combination of flex/bison
we needed this, clean it up a bit removing this.

Yeah, indeed, unsure if at that time the declaration was needed.

Ditto here, I'll remove the reference and rewrite the cset log a bit.
