From 7016383b44e855209aff47e56f11c59b8aa7b642 Mon Sep 17 00:00:00 2001 From: Dou Liyang Date: Fri, 17 Nov 2017 15:31:43 -0800 Subject: [PATCH] include/asm-generic/topology.h: remove unused parent_node() macro Commit a7be6e5a7f8d ("mm: drop useless local parameters of __register_one_node()") removed the last user of parent_node(). The parent_node() macro in generic situation is unnecessary. Remove it for cleanup.
