From: Martin Kaiser <martin@kaiser.cx>

These functions are referencing s3c...._clk_regs[], which are marked as
__initdata. When compiling with CONFIG_DEBUG_SECTION_MISMATCH=y, this
produces warnings like

WARNING: vmlinux.o(.text+0x198350):
Section mismatch in reference from the function s3c2410_clk_sleep_init()
to the (unknown reference) .init.data:(unknown)

Mark the s3c...._clk_sleep_init() functions as __init in
order to fix this.

Hi Martin,

The v2 patch is missing my reviewed-by tag[1].
[1] https://patchwork.kernel.org/patch/9535993/

Again, I add my reviewed-by tag.

The patch fixes the very first commit adding the driver:
"ca2e90a clk: samsung: add clock controller driver for s3c2412"
and it doesn't apply cleanly on top of that commit.
Still it applies cleanly up to v3.15 so I'll add the tag when
applying.
