This looks like a mistake while rebasing / updating the code which
resulted in commit 4262c38dc42e ("net: dsa: mv88e6xxx: Add SERDES stats
counters to all 6390 family members").
In light of what the commit which introduced this did, this patch looks
correct to me.
Fixes: 4262c38dc42e ("net: dsa: mv88e6xxx: Add SERDES stats counters to all
6390 family members")
