bind/unbind of USB host controller triggers resend of last CAN frame

[marckleinebudde]

To reproduce:

• bring up CANtact PRO as usual
• send a CAN frame
• unbind USB host controller:

  echo 2184200.usb | sudo tee /sys/bus/platform/drivers/imx_usb/bind
  

• bind the USB host controller:

  echo 2184200.usb | sudo tee /sys/bus/platform/drivers/imx_usb/bind
  

Actually send CAN frame, received by other system:

 (2021-12-14 23:23:56.860539)  can0  RX - -  111   [8]  FF 01 0A 0B 0C 0D 0E 22

Received CAN frame by other system after bind:

 (2021-12-14 23:24:07.573127)  can0  RX - -  111   [8]  FF 01 0A 0B 0C 0D 0E 22
