From 82f98705a4539cb209f863db7b02cd666b4a291c Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 1 Mar 2017 09:57:00 +0100 Subject: [PATCH] Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button count INPUT_PROP_BUTTONPAD is currently only set through the platform data. The RMI4 header doc says that this property is there to force the buttonpad property, so we also need to detect it by looking at the exported buttons count.
