[PATCH can 0/3] can: gs_usb: fix USB bulk in and out callbacks

[Marc Kleine-Budde]

The bulk-out callback gs_usb_xmit_callback() does not take care of the
cleanup of failed transfers of URBs. The 1st patch adds the missing
cleanup.

The bulk-in callback gs_usb_receive_bulk_callback() accesses the buffer of
the URB without checking how much data has actually been received. The last
2 patches fix this problem.
