    uncrustify: Ignore sp_arith to workaround bug
    
    A new bug in uncrustify 0.73 causes a pointer type to be interpreted
    as an arithmetic operation, thus adding a space. [0]
    
    This causes the CI pipeline to fail on style-check job.
    
    To workaround this, ignore the "space around arithmetic operator" rule.
