Sorry for the delay!

To summarize the status.

These patches look good:
[PATCH 01/12] can: kvaser_usb_leaf: Fix overread with an invalid command
[PATCH 02/12] can: kvaser_usb: Fix use of uninitialized completion
[PATCH 03/12] can: kvaser_usb: Fix possible completions during
init_completion
[PATCH 05/12] can: kvaser_usb_leaf: Set Warning state even without bus
errors
[PATCH 10/12] can: kvaser_usb_leaf: Fix wrong CAN state after stopping
[PATCH 12/12] can: kvaser_usb_leaf: Fix bogus restart events

This looks good, but see comment regarding explicit queue flush:
[PATCH 06/12] can: kvaser_usb_leaf: Fix TX queue out of sync after restart

I still need some more time looking into:
PATCH 07/12] can: kvaser_usb_leaf: Fix CAN state after restart
PATCH 08/12] can: kvaser_usb_leaf: Fix improved state not being reported
PATCH 11/12] can: kvaser_usb_leaf: Ignore stale bus-off after start

I want to replace
[PATCH 04/12] can: kvaser_usb: Mark Mini PCIe 2xHS as supporting error
counters
with a new patch
"can: kvaser_usb: kvaser_usb_leaf: Get capabilities from device"

I want to split the handling of CMD_ERROR_EVENT and the readback
functionality. I also want to add parameter readback for
kvaser_usb_hydra. I need more time to look over the can_bittiming_const
in kvaser_usb_leaf for the different supported firmware.
[PATCH 09/12] can: kvaser_usb_leaf: Fix silently failing bus params setup


I would like to create a V2 series, including my patches, if you are
okay with it?


Best regards,
jimmy
