HID: intel-ish-hid: Make remove callback return void
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct ishtp_cl_driver::remove() return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error value is a bad idea.
