Kukjin or Krzysztof, can you pick this up?

s3c2410_plls_add is a device notifier that may be called at runtime and is correctly not marked __init. However it calls s3c_plltab_register() which is marked __init, and that triggers a build error when we are checking for section mismatches: WARNING: vmlinux.o(.text+0x195e0): Section mismatch in reference from the function s3c2410_plls_add() to the function .init.text:s3c_plltab_register() The function s3c2410_plls_add() references the function __init s3c_plltab_register(). This is often because s3c2410_plls_add lacks a __init annotation or the annotation of s3c_plltab_register is wrong. This removes the __init annotation from s3c2410_plls_add as well as the __initdata section annotations from s3c2440_plls_12 and s3c2440_plls_169344, which in turn are referenced from s3c2410_plls_add.
