From 745d51dc8a29e00e9ba14e090aa3c8a41e7221d9 Mon Sep 17 00:00:00 2001 From: Yangtao Li Date: Thu, 22 Nov 2018 07:39:24 -0500 Subject: [PATCH] ata: pata_macio: add of_node_put() of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. This place doesn't do that, so fix it.
