The touch resistance calculation in the tsc2007 driver is prone to overflow if (z2 - z1) is large and also x is reasonably big. This overflow results in the driver emitting input events when very little touch pressure is applied. In these events the x and y coordinates can be substantially off. Avoid the overflow by using u64 when calculating resistance value.
