Subject: hwmon: pwm-fan: Use 64-bit division macro
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f3e4b14144a928c097e2d526f6dcd6ba0f5eba8a;p=linux.git

hwmon: pwm-fan: Use 64-bit division macro

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.
