I see that this is part of a large set, but the remainder of the patches have been hidden from me. Does this mean I can apply this patch on its own? > diff --git a/drivers/video/backlight/pwm_bl.c > b/drivers/video/backlight/pwm_bl.c > index efb4efc..3e5dbcf 100644 > --- a/drivers/video/backlight/pwm_bl.c > +++ b/drivers/video/backlight/pwm_bl.c > @@ -625,7 +625,8 @@ static int pwm_backlight_probe(struct platform_device > *pdev) > pb->scale = data->max_brightness; > } > > - pb->lth_brightness = data->lth_brightness * (state.period / pb->scale); > + pb->lth_brightness = data->lth_brightness * (div_u64(state.period, > + pb->scale)); > > props.type = BACKLIGHT_RAW; > props.max_brightness = data->max_brightness; -- Lee Jones [李琼斯] Linaro Services Technical Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
