From 899c537c25f9547a0f591ed2013be0f9f68f2df3 Mon Sep 17 00:00:00 2001 From: Guru Das Srinagesh Date: Tue, 2 Jun 2020 15:31:05 -0700 Subject: drm/i915: Use 64-bit division macro Since the PWM framework is switching struct pwm_state.duty_cycle's datatype to u64, prepare for this transition by using DIV_ROUND_UP_ULL to handle a 64-bit dividend.
