Merge patch series "can: usb: fix URB memory leaks"

Browse source

Marc Kleine-Budde <mkl@pengutronix.de> says:

An URB memory leak [1][2] was recently fixed in the gs_usb driver. The
driver did not take into account that completed URBs are no longer
anchored, causing them to be lost during ifdown. The memory leak was fixed
by re-anchoring the URBs in the URB completion callback.

Several USB CAN drivers are affected by the same error. Fix them
accordingly.
