[PATCH v1] drivers/base/node.c: get rid of get_nid_for_pfn()
From: David Hildenbrand
Date: Wed Nov 27 2019 - 12:41:38 EST
Since commit d84f2f5a7552 ("drivers/base/node.c: simplify
unregister_memory_block_under_nodes()") we only have a single user of
get_nid_for_pfn(). Let's just inline that code and get rid of
get_nid_for_pfn().
