I guess Jiada's concern that we are forcing to pass tool type even
though we end up ignoring it intervally, which confuses users of the API
as they might not know what tool to specify.
How about we do:
static inline void input_mt_report_slot_inactive(struct input_dev *dev)
input_mt_report_slot_state(dev, 0, false);
This should not change any behavior.
