I don't think so:

static struct subsys_interface s3c2442_plls169344_interface __initdata = {
.name = "s3c2442_plls169344",
.subsys = &s3c2442_subsys,
.add_dev = s3c2440_plls169344_add,

This gets passed into subsys_interface_register(), which is not __init
in turn. subsys_interface_register() then goes on to add
s3c2442_plls169344_interface into a linked list that is traversed
at runtime, but the __initdata section gets discarded so you now
have a broken list.
