Does this really fix a bug? If not, there's no need for cc: stable or:
Fixes: a0a927d06d79 ("mei: me: add io register tracing")

Without this patch the events are not emitted at all, they are dropped by trace security checker.
Ah, again, that was not obvious at all from the changelog. Perhaps reword it a bit? How has this ever worked?
