Subject: [PATCH v10 02/12] hwmon: pwm-fan: Use 64-bit division macro
Date: Thu, 19 Mar 2020 13:50:05 -0700 [thread overview]
Message-ID: <b8d8e51723f99844abc6a3f637ac42be3e084709.1584650604.git.gurus@codeaurora.org> (raw)

In-Reply-To: <cover.1584650604.git.gurus@codeaurora.org>
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.
