From 55bb1d8355ce91662dc8760f24f578db5a595819 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Mon, 25 Jan 2016 22:53:07 +0530 Subject: [PATCH] memory: tegra: mc: Add missing of_node_put() for_each_child_of_node() performs an of_node_get() on each iteration, so to break out of the loop an of_node_put() is required. Found using Coccinelle. The semantic patch used for this is as follows: // @@ expression e; local idexpression n; @@ for_each_child_of_node(..., n) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Thierry Reding --- drivers/memory/tegra/mc.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/memory/tegra/mc.c b/drivers/memory/tegra/mc.c index 85ce4beb7f03..a4803ac192bb 100644 --- a/drivers/memory/tegra/mc.c +++ b/drivers/memory/tegra/mc.c @@ -186,8 +186,10 @@ static int load_timings(struct tegra_mc *mc, struct device_node *node) timing = &mc->timings[i++]; err = load_one_timing(mc, timing, child); - if (err) + if (err) { + of_node_put(child); return err; + } } return 0; @@ -210,9 +212,9 @@ static int tegra_mc_setup_timings(struct tegra_mc *mc) continue; err = load_timings(mc, node); + of_node_put(node); if (err) return err; - of_node_put(node); break; } -- 2.20.1
