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.
