IMHO, that's a fragility on current devm implementation for input
devices, then.

devm_input_allocate_device() is *only* allocating the input device (at
least judging by the name). Looks like you should introduce
devm_input_register_device() ? What happens if I
devm_input_allocate_device() but don't go as far as
input_register_device() (some error happens in-between) ?

I'm sure you have some proper handling for it, but it's quite misleading
the way this was implemented.
