[PATCH v3 4/4] patman: Check patches in parallel

[Simon Glass]

For large series this can take a while. Run checkpatch in parallel to
try to reduce the time. The checkpatch information is still reported in
sequential order, so a very slow patch at the start can still slow
things down. But overall this gives good results.
