Some devices already had one. Some I had to add an empty one.
I did a little cleaning of init() methods to make them more uniform
but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
in case I want to revert these changes for some reason, for example
if they break an old patch. It should be deleted after a while.
