Subject: [PATCH net-next 08/10] net: dsa: mv88e6xxx: simplify SERDES code for Topaz and Peridot
Now that we have correct serdes_get_lane() for Topaz and Peridot
families, we can merge the implementations of their other SERDES
functions. We can skip checking port number, since the serdes_get_lane()
method return -ENODEV if a given port does not have a lane or does not
support given cmode.
