From 03b0a52822fec8fba351fd472f3adda6fd760e77 Mon Sep 17 00:00:00 2001 From: Igor Kotrasinski Date: Mon, 21 Sep 2015 11:30:44 +0200 Subject: usbip: vhci_hcd: only return urb at enqueue when served We handle USB_REQ_SET_ADDRESS at enqueue, so we want to perform cleanup and giveback the urb. We should not call usb_hcd_giveback_urb when we're cleaning up after a failed enqueue, though. Only giveback the urb at cleanup when we claim to have served it.
