From d1efa2a7551a10006055e0ac2870b4b6077df8ef Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 3 Aug 2010 09:50:32 +0000 Subject: [PATCH] powerpc/powermac: Drop unnecessary of_node_put for_each_node_by_name only exits when its first argument is NULL, and a subsequent call to of_node_put on that argument is unnecessary. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ iterator name for_each_node_by_name; expression np,E; identifier l; @@ for_each_node_by_name(np,...) { ... when != break; when != goto l; } ... when != np = E - of_node_put(np); // Signed-off-by: Julia Lawall Reviewed-by: Grant Likely Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/platforms/powermac/feature.c | 1 - arch/powerpc/platforms/powermac/pci.c | 2 -- 2 files changed, 3 deletions(-) diff --git a/arch/powerpc/platforms/powermac/feature.c b/arch/powerpc/platforms/powermac/feature.c index 39df6ab1735..6e26068a27c 100644 --- a/arch/powerpc/platforms/powermac/feature.c +++ b/arch/powerpc/platforms/powermac/feature.c @@ -2878,7 +2878,6 @@ set_initial_features(void) core99_airport_enable(np, 0, 0); } } - of_node_put(np); } /* On all machines that support sound PM, switch sound off */ diff --git a/arch/powerpc/platforms/powermac/pci.c b/arch/powerpc/platforms/powermac/pci.c index ab2027cdf89..3bc075c788e 100644 --- a/arch/powerpc/platforms/powermac/pci.c +++ b/arch/powerpc/platforms/powermac/pci.c @@ -1155,13 +1155,11 @@ void __init pmac_pcibios_after_init(void) pmac_call_feature(PMAC_FTR_1394_CABLE_POWER, nd, 0, 0); } } - of_node_put(nd); for_each_node_by_name(nd, "ethernet") { if (nd->parent && of_device_is_compatible(nd, "gmac") && of_device_is_compatible(nd->parent, "uni-north")) pmac_call_feature(PMAC_FTR_GMAC_ENABLE, nd, 0, 0); } - of_node_put(nd); } void pmac_pci_fixup_cardbus(struct pci_dev* dev) -- 2.20.1
