What is "blob function" ? Are you talking about all the phy_xxx() functions?

The ata bits looks OK, but this still feels like a lot of churn for no
functional change since the error is an internal one that is not exposed to the
user, as far as I can tell. The code in many places also uses -ENODEV, so the
error returned does not seem to be consistent anyway.
