Right, got it so avoid breaking it at all costs, in that case should we move
forward with the syzbot fix and the "remove extraneous return that
prevents error propagation" patches only? 

For the syzbot one we will return a negative on control read failure,
as the function already does that when encountering an invalid phy_id.

As for the "remove extraneous return that prevents error 
propagation" change it seems like a simple low risk change 
from what I can tell (if not please let me know).

Would you guys be happy with this?

Thanks
