I had grepped the commit log for other reverting patches, which also appear to
use this style, but I didn't check the regmap-specific ones.

If you would rather keep this, I should modify the other patch (regmap: mdio:
Reject invalid clause-22 addresses) to also cover C45 addresses.
Furthermore, there's an issue with a pointer const-ness in __regmap_init_mdio
that needs to be fixed if this code is staying.

I'll submit a v2 that fixes __regmap_init_mdio, and also applies the address
checks to C45 access.

Best,
Sander
