Subject: [PATCH can 0/3] can: drivers: drop skb in xmit if device is in
 listen only mode

I notived that 3 drivers (bxcan, esd and rockchip) use the function
can_dropped_invalid_skb(), that doesn't check if the device is in listen
only mode. This series converts these driver to use the new
can_dev_dropped_skb() function.

      can: esd: acc_start_xmit(): use can_dev_dropped_skb() instead of can_dropped_invalid_skb()
      can: rockchip-canfd: rkcanfd_start_xmit(): use can_dev_dropped_skb() instead of can_dropped_invalid_skb()
