Thanks. That much makes sense to me, and I'll put together a patch along
those lines.

But, further: with core coresight code assembling into the path all the
data that is necessary, is there any reason to be using void* in these
enable/disable functions?

Could we also change these functions to accept a coresight_path* and
actually get some compiler help at finding mistakes like the one we're
fixing here?
