Kind newspaperman’s fixed up (6)
I believe the answer is:
sorted
'fixed up' is the definition.
'kind newspaperman's' is the wordplay.
'kind' becomes 'sort' ('sort' can be a synonym of 'kind').
'newspaperman' becomes 'ed'.
'sort'+'ed'='SORTED'
(Other definitions for sorted that I've seen before include "Categorised" , "dealt with" , "Placed in desired sequence" , "Job done!" , "Put into correct sequence" .)
