3.16.63-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Marek Szyprowski <m.szyprow...@samsung.com>
commit f5e758b8358f6c27e8a351ddf0b441a64cdabb94 upstream.
PMIC_IRQB and PMIC_KEYINB lines on Exynos4210-based Origen board have
external pull-up resistors, so disable any pull control for those lines
in respective pin controller node. This fixes support for MAX8997
interrupts and enables operation of wakeup from MAX8997 RTC alarm.

Fixes: 17419726aaa1 ("ARM: dts: add max8997 device node for exynos4210-origen
board")
Signed-off-by: Krzysztof Kozlowski <k...@kernel.org>
[bwh: Backported to 3.16:
- Use literal 0 instead of EXYNOS_PIN_PULL_NONE
- Adjust context, indentation]
