In this case the xhci device representation vdev may be lost due to xHC restore error and re-initialization during S4 resume. Make sure slot_id and vdev are valid before trying to re-configure max packet size during endpoint 0 reset. max packet size will be re-configured later during re-enumeration. This fixes commit e34900f46cd6 ("xhci: Reconfigure endpoint 0 max packet size only during endpoint reset") which is currently in usb-next, on its way to 6.7You mean "6.8" here, right?
Ah, yes it should be 6.8, my mistake. Thanks Mathias
