    powerpc/macintosh: constify wf_sensor_ops structures · de854e54
    Julia Lawall authored
    The wf_sensor_ops structures are only stored in the ops field of a
    wf_sensor structure, which is declared as const.  Thus the
    wf_sensor_ops structures themselves can be const.
    
    Done with the help of Coccinelle.
