gb_vibrator_probe() maps any device_create() failure to -EINVAL. This loses the real errno returned by the driver core, such as -ENOMEM, and makes probe failures harder to diagnose correctly.

Return PTR_ERR(dev) instead so callers receive the actual failure reason while preserving the existing cleanup path.
