Merge branch 'next/gpio-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers
From Kukjin Kim:
This is for Samsung gpio stuff and got the ack from Linus Walleij.
* 'next/gpio-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
gpio: samsung: use pr_* instead of printk
gpio: samsung: Fix input mode setting function for GPIO int
ARM: SAMSUNG: Insert bitmap_gpio_int member in samsung_gpio_chip
