From 606bb5e0b28b540685fb94c22902cd9a948a3779 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 8 Oct 2015 11:43:34 +0300 Subject: [PATCH] drm/i915: Use round to closest when computing the CEA 1.001 pixel clocks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit drm_edid.c now computes the alternate CEA clocks using DIV_ROUND_CLOSEST(), so follow suit in the N/CTS setup to make sure we pick the right setting for the mode. Unfortunately we can't actually use DIV_ROUND_CLOSEST() here due to the ({}) construct used, so just stick in raw numbers instead.
