Hi everyone:

     On imx6 sdq, I found pwm_backlight_update_status was called and the pwm was disabled ,

In function pwm_backlight_update_status()(drivers/video/backlight/pwm_bl.)

{

...........

  pwm_config(pb->pwm, 0, pb->period);

  pwm_disable(pb->pwm);

...............

}

and then , I got the current process, it is kworker/1:2,  but I do not know how can the kworker trigger the pwm_backlight_update_status ???

Can anybody help me, thanks a lot .
