I needed to make some changes in the process (and fixed up some breakage reported by the auto build testing), hopefully I didn't break anything. If you're in an adventurous mood, testing would be welcome. ;-) [That already includes the majority of 3.11 material from Linus, though, so unexpected breakage elsewhere may happen.] Thanks, Rafael > drivers/pci/hotplug/acpiphp_glue.c | 25 ------------------------- > 1 file changed, 25 deletions(-) > > diff --git a/drivers/pci/hotplug/acpiphp_glue.c b/drivers/pci/hotplug/acpiphp_glue.c > index 62e09af..741504a 100644 > --- a/drivers/pci/hotplug/acpiphp_glue.c > +++ b/drivers/pci/hotplug/acpiphp_glue.c > @@ -760,25 +760,6 @@ static void acpiphp_sanitize_bus(struct pci_bus *bus) > * ACPI event handlers > */ > > -static acpi_status > -check_sub_bridges(acpi_handle handle, u32 lvl, void *context, void **rv) > -{ > - struct acpiphp_bridge *bridge; > - char objname[64]; > - struct acpi_buffer buffer = { .length = sizeof(objname), > - .pointer = objname }; > - > - bridge = acpiphp_handle_to_bridge(handle); > - if (bridge) { > - acpi_get_name(handle, ACPI_FULL_PATHNAME, &buffer); > - dbg("%s: re-enumerating slots under %s\n", > - __func__, objname); > - acpiphp_check_bridge(bridge); > - put_bridge(bridge); > - } > - return AE_OK ; > -} > - > void acpiphp_check_host_bridge(acpi_handle handle) > { > struct acpiphp_bridge *bridge; > @@ -788,9 +769,6 @@ void acpiphp_check_host_bridge(acpi_handle handle) > acpiphp_check_bridge(bridge); > put_bridge(bridge); > } > - > - acpi_walk_namespace(ACPI_TYPE_DEVICE, handle, > - ACPI_UINT32_MAX, check_sub_bridges, NULL, NULL, NULL); > } > > static void hotplug_event(acpi_handle handle, u32 type, void *data) > @@ -818,9 +796,6 @@ static void hotplug_event(acpi_handle handle, u32 type, void *data) > dbg("%s: re-enumerating slots under %s\n", __func__, objname); > if (bridge) { > acpiphp_check_bridge(bridge); > - acpi_walk_namespace(ACPI_TYPE_DEVICE, handle, > - ACPI_UINT32_MAX, check_sub_bridges, > - NULL, NULL, NULL); > } else { > struct acpiphp_slot *slot = func->slot; > > -- I speak only for myself.
