ARM: s3c: mark s3c2440_clk_add as __init_refok
s3c2440_clk_add is a subsys_interface method and calls clkdev_add_table,
which is marked as __init. The modpost script complains about this
because we must not call an __init function from a function in the .text
section, and we cannot reference an __init function from a subsys_interface
pointer.
I have verified that the only code path into s3c2440_clk_add() is
from "int __init s3c2440_init(void)", so s3c2440_clk_add can be marked
__init_refok instead.
Without this patch, building mini2440_defconfig results in:
WARNING: vmlinux.o(.text+0x9848): Section mismatch in reference from the function s3c2440_clk_add() to the function .init.text:clkdev_add_table()
The function s3c2440_clk_add() references
the function __init clkdev_add_table().
This is often because s3c2440_clk_add lacks a __init
annotation or the annotation of clkdev_add_table is wrong.
