Subject: [PATCH v13 03/11] ir-rx51: Use 64-bit division macro
Date: Tue, 21 Apr 2020 19:57:15 -0700	[thread overview]
Message-ID: <6466ddeafbe9b15aab0cdf393fb254fccab23a90.1587523702.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1587523702.git.gurus@codeaurora.org>
In-Reply-To: <cover.1587523702.git.gurus@codeaurora.org>

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