From 63ae7ebb0c6177efed46734061fb59c458a47a26 Mon Sep 17 00:00:00 2001
From: Saul Wold <sgw@linux.intel.com>
Date: Tue, 19 Jan 2016 09:49:19 -0800
Subject: [PATCH 2/2] configure.ac/Makefile.am: Check for input.h and
 input-event-codes.h

Add INPUT_HEADER to know which header file to use because it changed
in the 4.4 kernel code.

Set INPUT_HEADER with default linux/input.h if it exists and if the
newer input-events-codes.h exists from 4.4 use it instead.

Upstream-Status: Inappropriate [Upstream unsupported]
