Adding Bill Gatliff. Hi Kyungmin, Most of the driver looks fine. I have only one generic comment, but not for this driver: - Someone should really work on getting PWM framework (may be the one written by Bill Gatliff) into the kernel, because if we don't do this and if new PWM controller provides it's own APIs then we can't leverage the chips using them, like the case here for ISA1000 and ISA1200. These chips are using the pwm APIs exported by Samsung PWM controller, but it would be painful to integrate other PWM controller if that has slightly little different API due to its nature. So, it would be better to get one generic PWM framework mainline in the kernel. > +static int __devexit samsung_pwm_haptic_remove(struct platform_device *pdev) > +{ > + struct samsung_pwm_haptic *haptic = platform_get_drvdata(pdev); > + > + samsung_pwm_haptic_set(&haptic->cdev, HAPTIC_OFF); > + del_timer_sync(&haptic->timer); cancel_work_sync ? -- ---Trilok Soni http://triloksoni.wordpress.com http://www.linkedin.com/in/triloksoni -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
