[PATCH v9 02/11] hwmon: pwm-fan: Use 64-bit division macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since the PWM framework is switching struct pwm_args.period's datatype
to u64, prepare for this transition by using DIV_ROUND_UP_ULL to handle
a 64-bit dividend.
