Subject: [PATCH] memregion: Fix memregion_free() fallback definition
Git-commit: f50974eee5c4a5de1e4f1a3d873099f170df25f8
Patch-mainline: v5.19-rc6
References: git-fixes

In the CONFIG_MEMREGION=n case, memregion_free() is meant to be a static
inline. 0day reports:

    In file included from drivers/cxl/core/port.c:4:
    include/linux/memregion.h:19:6: warning: no previous prototype for
    function 'memregion_free' [-Wmissing-prototypes]

Mark memregion_free() static.
