Merge branch 'ionic-more-driver-fixes'

Shannon Nelson says:

====================
ionic: more driver fixes

These are a few code cleanup items that appeared first in a
separate net patchset,
    https://lore.kernel.org/netdev/20231201000519.13363-1-shannon.nelson@amd.com/
but are now aimed for net-next.
