This looks much better, thanks!

In the future, when updating a patch you should include a changelog here
below the '---' line and the patch revision should be indicated in the
Subject prefix (e.g. this should have been "[PATCH v3]: USB: serial:
...").

These defines should be sorted by PID.

And you have some stray whitespace after the comma here, which would
have been picked up by scripts/checkpatch.pl which you should run on
your patches before submitting them.
