Input: elan_i2c - fix calculating number of x and y traces. 2015-04-20T17:30:09+00:00 Duson Lin dusonlin@emc.com.tw 2015-04-20T17:19:24+00:00 9f423801c9e849df56b37833df895685c9d8a940 According to Elan's firmware engineers we should not be subtracting 1 form the raw number of x and y traces so that the pitch size is correct. For example, if the touchpad x resolution is 2800 and x trace number is 20, the pitch size of x should be 2800/20 = 140, not 2800/19 = 147.36.
