[PATCH net-next v3 2/8] net: dsa: mv88e6xxx: drop revision probing Vivien Didelot <vivien.didelot@savoirfairelinux.com> - 2016-04-17 00:50 +0200

| Subject | [PATCH net-next v3 2/8] net: dsa: mv88e6xxx: drop revision probing |
| Message-ID | <roHcn-2nN-29@gated-at.bofh.it> |
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.
