Subject: [PATCH v2] clk: samsung: mark s3c...._clk_sleep_init() as __init

From: Martin Kaiser <martin@...ser.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.

Signed-off-by: Martin Kaiser <martin@...ser.cx>

Fix the commit message, describe what the problem really is.
(Thanks, Krzysztof)
