clk: samsung: fix pm init on non-dt platforms
From: Heiko Stuebner <heiko@...> Date: Sun, 10 Mar 2013 13:12:53 +0100
Commit-Message
The clock_init function checked for a dt node, returning immediately for non-dt machines. This let to the suspend init never being reached on those non-DT machines. So fix this by moving the pm init code above the check. Signed-off-by: Heiko Stueber <heiko@...>
Patch-Comment
changes since v1: instead of removing the np check, move the pm init above it, as suggested by Thomas Abraham. When removing the np check the dt code is wrongly entered on non-dt machines if dt support is enabled in the kernel drivers/clk/samsung/clk.c | 25 +++++++++++++------------ 1 files changed, 13 insertions(+), 12 deletions(-)
