From 41a57850b5e5c450da351465efcc41383def7f8a Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 1 Apr 2013 19:18:18 +0100 Subject: extcon: arizona: Clear existing button reports before reporting new one If the user moves directly from one button to another then we won't get a no buttons pressed event and will therefore end up reporting that two buttons are simultaneously pressed which isn't supported by the hardware. Make sure we clear any existing button reports before reporting any new ones.
