From d99875eebfebec5432981273fac0547f3e34f2d7 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Fri, 22 Jan 2016 23:38:38 +0530 Subject: bus: vexpress-config: Add missing of_node_put for_each_compatible_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_compatible_node(n, ...) { ... when != of_node_put(n) when != e = n ( return n; + of_node_put(n); ? return ...; ) ... } // Acked-by: Liviu Dudau Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Sudeep Holla --- drivers/bus/vexpress-config.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'drivers/bus') diff --git a/drivers/bus/vexpress-config.c b/drivers/bus/vexpress-config.c index 6575c0fe6a4e..c3cb76b363c6 100644 --- a/drivers/bus/vexpress-config.c +++ b/drivers/bus/vexpress-config.c @@ -192,8 +192,10 @@ static int __init vexpress_config_init(void) /* Need the config devices early, before the "normal" devices... */ for_each_compatible_node(node, NULL, "arm,vexpress,config-bus") { err = vexpress_config_populate(node); - if (err) + if (err) { + of_node_put(node); break; + } } return err; -- cgit v1.2.3
