fix Touchpad cursor does not work after touching Touchpad by 3 or more fingers. Issue reproduction procedure 1.Three or more fingers put on Touchpad. 2.release fingers from Touchpad. 3.move the cursor by one finger. 4.the cursor does not move. Cause This code does not notify multi fingers state correctly to system. For example, when three fingers release from Touchpad, fingers state is 3 -> 0. It needs to notify first, second and third finger's releasing state. But this code does not notify second and third finger's releasing state by "break" code. Solution Delete "break" code, and move xyz input code to the correct place.
