[PATCH net-next 2/5] net: dsa: realtek: rtl8365mb: remove port_mask private data member

[Alvin Šipraga]

From: Alvin Šipraga <alsi@xxxxxxxxxxxxxxx>

There is no real need for this variable: the line change interrupt mask
is sufficiently masked out when getting linkup_ind and linkdown_ind in
the interrupt handler.
