Merge patch series "can: gs_usb: fix time stamp counter initialization"

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

During testing I noticed a crash if unloading/loading the gs_usb
driver during high CAN bus load.

The current version of the candlelight firmware doesn't flush the
queues of the received CAN frames during the reset command. This leads
to a crash if hardware timestamps are enabled, and an URB from the
device is received before the cycle counter/time counter
infrastructure has been setup.

First clean up then error handling in gs_can_open().

Then, fix the problem by converting the cycle counter/time counter
infrastructure from a per-channel to per-device and set it up before
submitting RX-URBs to the USB stack.
