mac->phy_node is acquired via of_parse_phandle() in spl2sw_probe() and
stored in the mac private data, transferring ownership of the
device_node reference to mac. On driver removal, spl2sw_phy_remove()
disconnects the PHY but never drops that reference, so each
probe-then-remove cycle leaks one of_node refcount per port permanently.

Drop the reference after phy_disconnect(). While at it, remove the
redundant inner "if (ndev)" check; comm->ndev[i] was just verified
non-NULL on the line above.

I assume you don't have this hardware, so this is untested? Please
state that in the commit message.

Does this issue bother people?
