From 341deefe8f4584b09564193cb46d8cf386f491a5 Mon Sep 17 00:00:00 2001 From: Philip Rakity Date: Tue, 11 Oct 2011 20:54:55 -0700 Subject: Input: tsc2007 - make sure that X plate resistance is specified Abort driver initialization if X plate resistance was not specified in platform data as it will cause pressure to be always calculated as 0, and making userspace ignore touch coordinates.
