I would disagree.  Quoting Documentation/CodingStyle

                Chapter 6: Functions

Functions should be short and sweet, and do just one thing.  They should
fit on one or two screenfuls of text (the ISO/ANSI screen size is 80x24,
as we all know), and do one thing and do that well.

dsa_cpu_dsa_setups iterates the ports and find the dsa and cpu ports
that need setting up.

dsa_cpu_dsa_setup() does the actual setup.

These are completely different things, and so should be in different
functions.
