Subject: initramfs: mark my_inptr as __initdata
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=199cda13534f4c676d7e4601665e971f4f0582c4;p=linux.git

initramfs: mark my_inptr as __initdata

As my_inptr is only used in __init function unpack_to_rootfs(), mark it as
__initdata to allow it be freed after boot.
