Subject: ACPI: NUMA: HMAT: fix a section mismatch
Patch-mainline: v5.5-rc1
Git-commit: 59b2c5b63587a9ed2292ccce32fd69d8de815036
References: jsc#SLE-16407

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().

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 that the __init annotation of
hmat_register_target_devices() is incorrect.
