If you are going to submit patches for comma/semicolon conversions,
please to not use checkpatch to produce them.

checkpatch is a trivial tool that does not have very good coverage
of the possible uses of commas that would generally be written with
a semicolon.

Use the coccinelle script that Julia Lawall provided instead.

This misses these 2 uses in tools/perf.
