From 2b88ff4a75f2175902389e3356d6227d7030e382 Mon Sep 17 00:00:00 2001 From: Eunki Kim Date: Tue, 23 Oct 2012 22:39:38 +0900 Subject: gpio: samsung: Fix input mode setting function for GPIO int This patch makes GPIO pin to INTERRUPT mode or INPUT mode according to bitmap_gpio_int. When the related bit of bitmap_gpio_int is set, it makes GPIO pin to INTERRUPT mode instrad of INPUT mode in the samsung_gpiolib_4bit_input function.
