[PATCH net-next v4 3/9] net: dsa: mv88e6xxx: drop revision probing

From: Vivien Didelot
Date: Sun Apr 17 2016 - 13:26:33 EST


There is no point in having a special case for the revision when probing
a switch model. The code gets cluttered with unnecessary defines, and
leads to errors when code such as mv88e6131_setup compares
PORT_SWITCH_ID_6131_B2 to ps->id which masks the revision.

Drop every revision definition, and lookup only the product number.
