Hi Richard - There's 3 of these patches in a row, so I'll share
the common ask here. How about replacing vague 'Show message'
with type of message like "Add [dev_dbg() | dev_warn() | dev_err()]...
I think there is one of each flavor.
For this one, are you able to append here what it looks like
when there is a broken target list during region creation.
ie...put in context how this message fits into the full spew.
