From fb5e4c3ee140b29e1935b4bbb19c319177bed231 Mon Sep 17 00:00:00 2001 From: Nick Dyer Date: Sun, 18 May 2014 23:00:15 -0700 Subject: Input: atmel_mxt_ts - improve T19 GPIO keys handling * The mapping of the GPIO numbers into the T19 status byte varies between different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array of up to 8 items is simpler and more generic. So replace #define with configurable number of keys which also allows the removal of is_tp. * Rename platform data parameters to include "t19" to prevent confusion with T15 key array. * Probe aborts early on when pdata is NULL, so no need to check. * Move "int i" to beginning of function (mixed declarations and code) * Use API calls rather than __set_bit() * Remove unused dev variable.
