Hmm, I guess we are better now with cleaning and turning devices into

No, that wasn't the silly part of your statement.

The silly part is that

  dev_set_name(&dev->dev, "input-%s", dev_name(dev->dev.parent));

works perfectly fine if the parent goes away, for a damn simple
reason: it generates the string *once*, and doesn't care one *whit*
about the parent pointer ever again afterwards.

For exactly the same that your current

  dev_set_name(&dev->dev, "input%d", atomic_inc_return(&input_no) - 1);

doesn't care *at*all* about that "input_no" variable afterwards -
dev_set_name() will have turned it into a string, and "input_no" can
change as much as it wants, and that won't change the name of the
device.

See? So no "refcounting parents" or "zombie devices" or any crap like
that. The name is just a string.

Anyway, I can't be bothered to argue. If you think "input1" is such a
great name, and then that results in nobody actually ever *using* it
because everybody agrees it useless and will use something else,
whatever.
