Patch series "mm/memory_hotplug: cleanup do_migrate_range()".
Make do_migrate_range() return value mechanism simple.
This patch (of 2):
Return value mechanism of do_migrate_range() is not very simple, while
no caller of the function checks the return value. Make the function
return nothing to be more simple.
