If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From faeed51bb65ce0241052d8dc24ac331ade12e976 Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov <dbaryshkov@xxxxxxxxx> Date: Thu, 15 Jan 2015 05:00:37 +0300 Subject: power: gpio-charger: balance enable/disable_irq_wake calls From: Dmitry Eremin-Solenikov <dbaryshkov@xxxxxxxxx> commit faeed51bb65ce0241052d8dc24ac331ade12e976 upstream. enable_irq_wakeup returns 0 in case it correctly enabled the IRQ to generate the wakeup event (and thus resume should call disable_irq_wake). Currently gpio-charger driver has this logic inverted. Correct that thus correcting enable/disable_irq_wake() calls balance.
