I wonder if we still need to return opp_table from here, or a simple
integer is fine.. The callers shouldn't be required to use the OPP
table directly anymore I believe and so better simplify the return
part of this and all other routines you are adding here..

If there is a user which needs the opp_table, let it use the regular
non-devm variant.
