However returning an error code in the remove callback doesn't accomplish that. Instead set the suppress_bind_attrs property (which makes it impossible to unbind the driver via sysfs). The only remaining way to unbind a sh_tmu2 device would be module unloading, but that doesn't apply here, as the driver cannot be built as a module. Also drop the useless remove callback.
