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 .
