====================
Fix 2 non-critical issues in SJA1105 DSA

This small series suppresses the W=1 warnings in the sja1105 driver and
it corrects some register offsets. I would like to target it against
net-next since it would have non-trivial conflicts with net, and the
problems it solves are not that big of a deal.
