From 15b8dd53f5ffaf8e2d9095c423f713423f576c0f Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 29 Jun 2009 13:39:29 +0800 Subject: ACPICA: Major update for acpi_get_object_info external interface Completed a major update for the acpi_get_object_info external interface. Changes include: - Support for variable, unlimited length HID, UID, and CID strings - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) - Call the _SxW power methods on behalf of a device object - Determine if a device is a PCI root bridge - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. These changes will require an update to all callers of this interface. See the ACPICA Programmer Reference for details. Also, update all invocations of acpi_get_object_info interface Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown --- drivers/acpi/acpi_memhotplug.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) (limited to 'drivers/acpi/acpi_memhotplug.c') diff --git a/drivers/acpi/acpi_memhotplug.c b/drivers/acpi/acpi_memhotplug.c index 9a62224cc27..80eacbe157e 100644 --- a/drivers/acpi/acpi_memhotplug.c +++ b/drivers/acpi/acpi_memhotplug.c @@ -481,26 +481,23 @@ static acpi_status is_memory_device(acpi_handle handle) { char *hardware_id; acpi_status status; - struct acpi_buffer buffer = { ACPI_ALLOCATE_BUFFER, NULL }; struct acpi_device_info *info; - - status = acpi_get_object_info(handle, &buffer); + status = acpi_get_object_info(handle, &info); if (ACPI_FAILURE(status)) return status; - info = buffer.pointer; if (!(info->valid & ACPI_VALID_HID)) { - kfree(buffer.pointer); + kfree(info); return AE_ERROR; } - hardware_id = info->hardware_id.value; + hardware_id = info->hardware_id.string; if ((hardware_id == NULL) || (strcmp(hardware_id, ACPI_MEMORY_DEVICE_HID))) status = AE_ERROR; - kfree(buffer.pointer); + kfree(info); return status; } -- cgit v1.2.3
