Subject: [PATCH] init: Fix section mismatch on do_mounts_md.c

From: Rakib Mullick <rakib.mullick@...il.com>

This patch fixes the following warnings. autodetect_raid(void)
function lacks __init since
it refers to __initdata raid_autopart.	

  LD      init/mounts.o
WARNING: init/mounts.o(.text+0x20c): Section mismatch in reference
from the function autodetect_raid() to the variable
.init.data:raid_autopart
The function autodetect_raid() references
the variable __initdata raid_autopart.
This is often because autodetect_raid lacks a __initdata
annotation or the annotation of raid_autopart is wrong.

  LD      init/built-in.o
WARNING: init/built-in.o(.text+0x434): Section mismatch in reference
from the function autodetect_raid() to the variable
.init.data:raid_autopart
The function autodetect_raid() references
the variable __initdata raid_autopart.
This is often because autodetect_raid lacks a __initdata
annotation or the annotation of raid_autopart is wrong.
