Can you explain why? My assumption would be that either
(a) we don't need the kernel's PMU, in which case don't
create it at all, or
(b) we do need the kernel's PMU, so we should both create
and INIT it.
If we do one but not the other then we've left a half
created and unusable PMU device in the kernel, haven't we?
thanks
