Jiri Olsa f17aafae9e perf: Remove superfluous allocation error check ... commit bfb3d7b8b9 upstream. If the get_callchain_buffers fails to allocate the buffer it will decrease the nr_callchain_events right away. There's no point of checking the allocation error for nr_callchain_events > 1. Removing that check.
