From 2263576cfc6e8f6ab038126c3254404b9fcb1c33 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Fri, 13 Nov 2009 10:06:08 +0800 Subject: ACPICA: Add post-order callback to acpi_walk_namespace The existing interface only has a pre-order callback. This change adds an additional parameter for a post-order callback which will be more useful for bus scans. ACPICA BZ 779. Also update the external calls to acpi_walk_namespace. http://www.acpica.org/bugzilla/show_bug.cgi?id=779 Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Len Brown --- drivers/pci/hotplug/acpi_pcihp.c | 2 +- drivers/pci/hotplug/acpiphp_glue.c | 22 +++++++++++----------- drivers/pci/hotplug/acpiphp_ibm.c | 2 +- 3 files changed, 13 insertions(+), 13 deletions(-) (limited to 'drivers/pci/hotplug') diff --git a/drivers/pci/hotplug/acpi_pcihp.c b/drivers/pci/hotplug/acpi_pcihp.c index a73028ec52e..0f32571b94d 100644 --- a/drivers/pci/hotplug/acpi_pcihp.c +++ b/drivers/pci/hotplug/acpi_pcihp.c @@ -471,7 +471,7 @@ int acpi_pci_detect_ejectable(acpi_handle handle) return found;
