From 3d4af5cac77f8d4f7422b1d00cb9e67000f94301 Mon Sep 17 00:00:00 2001 From: Atul Dahiya Date: Fri, 8 Oct 2010 21:00:02 +0900 Subject: [PATCH] ARM: S5P64X0: Fix GPIO rbank support The patch removes s3c_gpio_lock/unlock to avoid acquiring the lock recursively as lock is already acquired by calling function.
