Olivier Sobrie e59e36e733 can: kvaser_usb: add retries/timeout to kvaser_usb_wait_msg() ... On some Kvaser hardware, the firmware returns extra messages after the request for card info. For instance on a Leaf Light v2: --> CMD_GET_CARD_INFO <-- CMD_USB_THROTTLE <-- CMD_GET_CARD_INFO2 <-- CMD_GET_CARD_INFO_REQ When it happens, the probing function fails because we only read the first usb message. To overcome this issue, we add a mechanism of retries to the kvaser_usb_wait_msg() function. I tested this patch with the following hardware: - Kvaser Leaf Light - Kvaser Leaf Light v2 - Kvaser USBCan R This patch is necessary for the Leaf Light v2 hardware.
