Subject: [PATCH] perf lock: Remove redundant word 'contention' in help message

Before:
  # perf lock -h

   Usage: perf lock [<options>] {record|report|script|info|contention|contention}

      -D, --dump-raw-trace  dump raw trace in ASCII
      -f, --force           don't complain, do it
      -i, --input <file>    input file name
      -v, --verbose         be more verbose (show symbol address, etc)
          --kallsyms <file>
                            kallsyms pathname
          --vmlinux <file>  vmlinux pathname

After:
  # perf lock -h

   Usage: perf lock [<options>] {record|report|script|info|contention}

      -D, --dump-raw-trace  dump raw trace in ASCII
      -f, --force           don't complain, do it
      -i, --input <file>    input file name
      -v, --verbose         be more verbose (show symbol address, etc)
          --kallsyms <file>
                            kallsyms pathname
          --vmlinux <file>  vmlinux pathname
