Vladimir Oltean says:

====================
Fixups for qca8k ds->user_mii_bus cleanup

The series "ds->user_mii_bus cleanup (part 1)" from the last development
cycle:
https://patchwork.kernel.org/project/netdevbpf/cover/20240104140037.374166-1-vladimir.oltean@nxp.com/

had some review comments I didn't have the time to address at the time.
One from Alvin and one from Luiz. They can reasonably be treated as
improvements for v6.9.
