Subject: mm/memory_hotplug: add mhp_online_type_to_str() and export string helpers
Date: Sun, 12 Jul 2026 11:44:56 -0400

Add mhp_online_type_to_str() as the inverse of mhp_online_type_from_str(),
and export both so a driver can render and parse the memory online type
through its own sysfs interface.
