Dear Maintainer,

With linux-image-5.10.0-8-amd64, Microchip CAN BUS Analyzer does not
work with mcba_usb device driver.

The same device works with linux-image-5.10.0-7-amd64:

> Jul 09 17:46:58 leno kernel: mcba_usb 1-6:1.0 can0: device disconnected
> Jul 09 17:46:58 leno kernel: device can0 left promiscuous mode
