From: Bjorn Andersson <quic_bjora...@quicinc.com>
The dp_aux write operations takes the data to be operated on through a
member of struct dp_catalog, rather than as an argument to the function.
No state is maintained other than across the calling of the functions,
so replace this member with a function argument.
