From f10513de2a6036742b55e23278f0322f2e5c3772 Mon Sep 17 00:00:00 2001 From: Benson Leung Date: Wed, 6 Apr 2011 16:55:20 -0700 Subject: gpio-charger: Add gpio_charger_resume Gpio charger should notify if the gpio state had changed during suspend. This will send a CHANGED event each time the system resumes, ensuring a plug/unplug of the charger is not missed.
