Same spot/declarations that triggered a build error on v2 and fixed in v3 but moved to void * in v4 rather than defining an empty arm_pmu struct due to v3 feedback.
Notably I remembered to build this branch before sending this time but these definitions do not trigger an error or warning on gcc-14 with this .config and W=1. So I'm not sure how I could have reasonably caught this myself before sending.
Anyway, I'll fix. It's nothing to give the parameters a name.
