    pwm: mtk-disp: Don't check the return code of pwmchip_remove()
    
    [ Upstream commit 9b7b5736ffd5da6f8f6329ebe5f1829cbcf8afae ]
    
    pwmchip_remove() returns always 0. Don't use the value to make it
    possible to eventually change the function to return void. Also the
    driver core ignores the return value of mtk_disp_pwm_remove().
