The Ethernet connect path stores that\ndevice in mac->mc_dev and keeps it for the lifetime of the connected MAC\nobject.\n\nHowever, the disconnect path only disconnects and closes the MAC before\nfreeing the dpaa2_mac object. It does not drop the endpoint device\nreference stored in mac->mc_dev, so every successful connect leaks that\ndevice reference when the MAC is later disconnected.\n\nDrop the endpoint device reference after closing the MAC and before\nfreeing the dpaa2_mac object."
