Thanks, applying and adding the missing Fixes line:

Fixes: aa441895f7b4 ("perf report: Compare symbol name for inlined frames when sorting")

Also added Millian, the author of that patch to the Cc list, so that he
can check this as well if he has the time for doing so.

Please double check that this indeed is when this problem was
introduced,
