Are upset about no good passion (5)
I believe the answer is:
anger
'passion' is the definition.
(I've seen this in another clue)
'are upset about no good' is the wordplay.
'upset' indicates an anagram.
'about' means one lot of letters goes inside another.
'no good' becomes 'ng' (abbreviation).
'are' anagrammed gives 'aer'.
'aer' enclosing 'ng' is 'ANGER'.
(Other definitions for anger that I've seen before include "Heat" , "Strong displeasure" , "blaze of this?" , "Provoke annoyance" , "Strongly annoy" .)
