[PATCH -next] acpi/numa/hmat: fix a section mismatch

From: Qian Cai
Date: Mon Nov 11 2019 - 16:34:58 EST


The commit cf8741ac57ed ("ACPI: NUMA: HMAT: Register "soft reserved"
memory as an "hmem" device") introduced a linker warning,

WARNING: vmlinux.o(.text+0x64ec3c): Section mismatch in reference from
the function hmat_register_target() to the function
.init.text:hmat_register_target_devices()
The function hmat_register_target() references
the function __init hmat_register_target_devices().
This is often because hmat_register_target lacks a __init
annotation or the annotation of hmat_register_target_devices is wrong.

Since hmat_register_target() is also called from hmat_callback(), and
then register_hotmemory_notifier() where it should not be freed when
hmat_init() is done, it indicates the annotation of
hmat_register_target_devices() is incorrect.
