perf data: Correct -h output
There is currently only 1 'perf data' command, but supporting extra commands was breaking the help output. Simplify for now so that the help output is correct. Before: $ perf data -h Usage: perf data [<common options>] <command> [<options>] $ perf data Usage: perf data [<common options>] <command> [<options>] Available commands: convert - converts data file between formats After: $ perf data Usage: perf data convert [<options>] -f, --force don't complain, do it -i, --input <file> input file name -v, --verbose be more verbose --all Convert all events --to-ctf ... Convert to CTF format --to-json ... Convert to JSON format --tod Convert time to wall clock time $ perf data -h Usage: perf data convert [<options>] -f, --force don't complain, do it -i, --input <file> input file name -v, --verbose be more verbose --all Convert all events --to-ctf ...
