From 47918bc68b7427e961035949cc1501a864578a69 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 27 Nov 2018 19:16:44 +1100 Subject: powerpc/pseries: Fix node leak in update_lmb_associativity_index() In update_lmb_associativity_index() we lookup dr_node using of_find_node_by_path() which takes a reference for us. In the non-error case we forget to drop the reference. Note that find_aa_index() does modify properties of the node, but doesn't need an extra reference held once it's returned.
