From 636d0375e7a850c95a0abc2c214295ce06cd2ab4 Mon Sep 17 00:00:00 2001 From: Bjorn Van Tilt Date: Mon, 24 Mar 2014 15:32:08 +0100 Subject: [PATCH] can: usb_8dev: Fix memory leak in usb_8dev_start_xmit Fixed a memory leak when an error occurred in the transmit function. In the error handling the urb wasn't freed before returning. There was also a call to the usb_unanchor_urb() function but the urb wasn't anchored.
