From: Julia Lawall <ju...@diku.dk> 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/) // <smpl> @@ 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); // </smpl> Signed-off-by: Julia Lawall <ju...@diku.dk> --- arch/powerpc/platforms/powermac/feature.c | 1 - arch/powerpc/platforms/powermac/pci.c | 2 -- 2 files changed, 3 deletions(-) diff -u -p a/arch/powerpc/platforms/powermac/feature.c b/arch/powerpc/platforms/powermac/feature.c --- a/arch/powerpc/platforms/powermac/feature.c +++ b/arch/powerpc/platforms/powermac/feature.c @@ -2872,7 +2872,6 @@ 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 -u -p a/arch/powerpc/platforms/powermac/pci.c b/arch/powerpc/platforms/powermac/pci.c --- 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) _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
