When submitting code you didn't write, I'd say it's better practice to
clearly indicate its provenance in the commit message. E.g. something
like "Driver based on code authored by Ludovic Barre for ST". And
obtain signoffs etc if possible.

Please review the wording here. It's unclear whether this is intended
to be v2-only or v2 or later.

Seems like st_rproc_stop should propagate errors back to its caller
instead of always returning 0.
