    pwm: meson: Make use of pwmchip_parent() accessor
    
    [ Upstream commit e369035a98894a7327e78ebd01ec859c6654fc52 ]
    
    struct pwm_chip::dev is about to change. To not have to touch this
    driver in the same commit as struct pwm_chip::dev, use the accessor
    function provided for exactly this purpose.
