'put right' is the definition.
(I've seen this before)

'chap put wrongly?' is the wordplay.
'wrongly?' indicates anagramming the letters (I've seen 'wrongly' mean this).

'chapput' anagrammed gives 'PATCH-UP'.

'what the' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
