From 3c152165c78408e44845f2d08469db887f050e43 Mon Sep 17 00:00:00 2001 From: Minkyu Kang Date: Mon, 27 Dec 2010 15:55:48 +0900 Subject: [PATCH] armv7: s5pc1xx: don't use function pointer for clock functions Because of the bss area is cleared after relocation, we've lost pointers. This patch fixed it.
