[PATCH v2] mfd: max8997: Enale irq-wakeup unconditionally

From: Marek Szyprowski
Date: Wed Sep 05 2018 - 07:54:27 EST


IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.
