The debug message is still there. Except now it runs only if no errors
have occurred to preserve the previous behavior, where the line 
wouldn't have run in the case of an early return.

The difference between the new multi variants of the functions and the 
old functions is that multi functions don't run if an error has 
occurred previously (thus removing need for early returns), and they 
call dev_err internally in the case of an error, thus letting us know 
where the error occurred without explicitly having to do error handling 
in the call site.
