Merge branch 'fixes-for-3.11' of git://gitorious.org/linux-can/linux-can

Marc Kleine-Budde says:

====================
here are two fixes for the v3.11 release cycle:

Maximilian Schneider contributes a patch for the esd_usb2 CAN driver. It adds
sanity checking to the data coming from the USB CAN adapter before using it.
Alexey Khoroshilov from the Linux Driver Verification project fixes an urb leak
in the error handling of the USB 8dev's usb_8dev_start() function.
