From 91630955cb4c9899aa4521d1459837c66c5e9c7a Mon Sep 17 00:00:00 2001 From: Daniel Kurtz Date: Thu, 28 Jun 2012 21:08:09 +0800 Subject: [PATCH] Input: atmel_mxt_ts - print less overhead when dumping objects Conserve limited (PAGE_SIZE) sysfs output buffer space by only showing readable objects and not printing the object's index, which is not useful to userspace.
