[PATCH 01/10] x86/efi: Mark can_free_region() as an __init function

From: Ard Biesheuvel
Date: Sat Feb 02 2019 - 04:42:24 EST


From: Sai Praneeth Prakhya <sai.praneeth.prakhya@xxxxxxxxx>

can_free_region() is called only once during _boot_ by
efi_reserve_boot_services(). Hence, mark it as __init function.
