Even though the patch is obvious, it should have at least one line of
description.

We still have non-DT platforms which use this code, i.e. s3c24xx and
s3c64xx. Have you checked if this compiles fine on them with CONFIG_OF
disabled?

Compile tested with s3c2410_defconfig and s3c6400_defconfig, and its
compiled fine.
In both cases CONFIG_OF was disabled.

I've dropped this change when applying since it causes a build break:

drivers/clk/samsung/clk.c:338:15: error: variable ?samsung_clk_syscore_ops? has initializer but incomplete type
drivers/clk/samsung/clk.c:339:2: error: unknown field ?suspend? specified in initializer

Please make sure there is no build breaks with various configs when
sending patches.

I am sure that I compile tested this before submitting. Looks like 
following commit [1] needs "linux/syscore-ops.h" in clk.c, before that 
it was not needed.

1: clk: samsung: Factor out the common code to clk.c [SHA_ID: 
16a9013b83b5106c83cf]

Anyways, I can see patches are not getting cleanly applied so, just now 
I resend them [2] after rebasing please have a look.

OK, my apologies then for not investigating it further.

There is no need to resend, the patches are already applied into
my tree

git://linuxtv.org/snawrocki/samsung.git for-v3.19/clk-next

I will probably send a second pull request for Mike today.
Just need to figure out what to do with the patches addressing
the dependency of the audio clock controller control registers
on the APLL clock.
