Subject: [PATCH net-next v4 4/6] net: dsa: mv88e6xxx: simplify SERDES code for Topaz and Peridot
By adding an additional serdes_get_lane implementation (for Topaz), we
can merge the implementations of other SERDES functions (powering and
IRQs). We can skip checking port numbers, since the serdes_get_lane()
methods inform if there is no lane on a port or if the lane cannot be
used for given cmode.
