    drivers/base/devtmpfs.c: correct annotation of `setup_done'

    This fixes the following section mismatch issue:

    WARNING: vmlinux.o(.text+0x1192bf): Section mismatch in reference
from the function devtmpfsd() to the variable .init.data:setup_done
    The function devtmpfsd() references the variable __initdata setup_done.
    This is often because devtmpfsd lacks a __initdata annotation or
the annotation of setup_done is wrong.

    WARNING: vmlinux.o(.text+0x119342): Section mismatch in reference
from the function devtmpfsd() to the variable .init.data:setup_done
    The function devtmpfsd() references the variable __initdata setup_done.
    This is often because devtmpfsd lacks a __initdata annotation or
the annotation of setup_done is wrong.
