[PATCH v2 1/1] acpi/hmat: preserve hmat_adist_nb notifier block

From: Alejandro Lucero <[email protected]>

Remove __meminitdata from hmat_adist_nb declaration preserving it even
when CONFIG_MEMORY_HOTPLUG is not set. Otherwise further notifier
registrations using register_mt_adistance_algorithm() will find a
notifier chain likely corrupted.

This is the case when cxl_region_probe() calls
register_mt_adistance_algorithm() what can happen when CXL regions
are dynamically created at any time from Type3 device(s) or when a Type2
device is initialized at its driver probe.

Fixes: 3718c02dbd4c ("acpi, hmat: calculate abstract distance with HMAT")
