for_each_child_of_node performs an of_node_get on each iteration, so no of_node_get is needed on breaking out of the loop when the device_node structure is saved in another variable. A simplified semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root; local idexpression child; @@ for_each_child_of_node(root, child) { ... * of_node_get(child) ... break; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- arch/mips/pci/pci-rt3883.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/arch/mips/pci/pci-rt3883.c b/arch/mips/pci/pci-rt3883.c index ed6732f..53a42b0 100644 --- a/arch/mips/pci/pci-rt3883.c +++ b/arch/mips/pci/pci-rt3883.c @@ -432,8 +432,7 @@ static int rt3883_pci_probe(struct platform_device *pdev) /* find the interrupt controller child node */ for_each_child_of_node(np, child) { - if (of_get_property(child, "interrupt-controller", NULL) && - of_node_get(child)) { + if (of_get_property(child, "interrupt-controller", NULL)) { rpc->intc_of_node = child; break; } @@ -449,8 +448,7 @@ static int rt3883_pci_probe(struct platform_device *pdev) /* find the PCI host bridge child node */ for_each_child_of_node(np, child) { if (child->type && - of_node_cmp(child->type, "pci") == 0 && - of_node_get(child)) { + of_node_cmp(child->type, "pci") == 0) { rpc->pci_controller.of_node = child; break; } -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
