perf record: Fix documentation for a inexistent option '-l'
'perf record' had a '-l' option that meant "scale counter values" a very long time ago, but it currently belongs to 'perf stat' as '-c'. So remove it. I found this problem in the below case. $ perf record -e cycles -l sleep 3 Error: unknown switch `l Signed-off-by: Taeung Song <treeze.taeung@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1507907412-19813-1-git-send-email-treeze.taeung@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
