Looks good, though I do have one comment ...

You removed the dev_info from the mfd driver but left it in the client
drivers.  If you'd drop it here as well, you could use
'return PTR_ERR_OR_ZERO(hwmon_dev);'.  Just a suggestion, not mandatory.

Either case,

I assume this will go in through the mfd tree.

Thanks,
Guenter
