UefiDevicePathLibConvertTextToDevicePath correctly detects when it
has hit a ',' splicing together multiple paths. However, the code
that tries to cope with it:
{code}
if (IsInstanceEnd) {
DeviceNode = (EFI_DEVICE_PATH_PROTOCOL *) AllocatePool (
END_DEVICE_PATH_LENGTH);
ASSERT (DeviceNode != NULL);
SetDevicePathEndNode (DeviceNode);
NewDevicePath = AppendDevicePathNode (DevicePath, DeviceNode);
FreePool (DevicePath);
FreePool (DeviceNode);
DevicePath = NewDevicePath;
}
{code}
causes a problem. The END node that's appended it the node for the
entire list. So when the node is appended in AppendDevicePathNode,
it winds up disappearing. This leads to the path
'PciRoot(0x0),PciRoot(0x0)' parsing as if 'PciRoot(0x0)/PciRoot(0x0)'
were specified. These are two very different things.
