From 5394ba0fd892291eb425649fdbc82b673e0b7956 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 5 Aug 2008 13:01:28 -0700 Subject: drivers/video/fsl-diu-fb.c: add missing of_node_put of_node_put is needed before discarding a value received from of_find_node_by_type, eg in error handling code. The semantic patch that makes the change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ struct device_node *n; struct device_node *n1; struct device_node *n2; statement S; identifier f1,f2; expression E1,E2; constant C; @@ n = of_find_node_by_type(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f1(n,...) when != E1 = n when any when strict ( + of_node_put(n); return -C; | of_node_put(n); | n2 = f2(n,...) | E2 = n | return ...; ) // Signed-off-by: Julia Lawall Acked-by: Krzysztof Helt Cc: Timur Tabi Cc: York Sun Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/video/fsl-diu-fb.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/video/fsl-diu-fb.c b/drivers/video/fsl-diu-fb.c index 9cd36c223d33..bd320a2bfb7c 100644 --- a/drivers/video/fsl-diu-fb.c +++ b/drivers/video/fsl-diu-fb.c @@ -1649,8 +1649,10 @@ static int __init fsl_diu_init(void) } prop = of_get_property(np, "d-cache-size", NULL); - if (prop == NULL) + if (prop == NULL) { + of_node_put(np); return -ENODEV; + } /* Freescale PLRU requires 13/8 times the cache size to do a proper displacement flush @@ -1659,8 +1661,10 @@ static int __init fsl_diu_init(void) coherence_data_size /= 8; prop = of_get_property(np, "d-cache-line-size", NULL); - if (prop == NULL) + if (prop == NULL) { + of_node_put(np); return -ENODEV; + } d_cache_line_size = *prop; of_node_put(np); -- cgit v1.2.3
