Agreed, it isn't ideal visually, but is at least more unique than priv.
Linus was going for short names recently (e.g. gc for gpiochip), so I was
going for something short.

And I try avoid names ending in _data or _state or similar where they
don't really add anything.

Would chardev or gchardev work for you?
