From 7571f089d7522a95c103558faf313c7af8856ceb Mon Sep 17 00:00:00 2001 From: =?utf8?q?M=C3=A1rton=20N=C3=A9meth?= Date: Mon, 13 Dec 2010 21:59:09 +0100 Subject: [PATCH] staging: usbip: remove double giveback of URB MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In the vhci_urb_dequeue() function the TCP connection is checked twice. Each time when the TCP connection is closed the URB is unlinked and given back. Remove the second attempt of unlinking and giving back of the URB completely. This patch fixes the bug described at https://bugzilla.kernel.org/show_bug.cgi?id=24872 .
