From 96525a2f7448c427bb8d99240907a6bd2d9e818c Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 14 May 2010 13:06:19 +0200 Subject: [PATCH] drm_edid: There should be 6 Standard Timings Smatch complained that we initialize 6 elements in add_detailed_modes() but the timings[] array is declared with 5 elements. Adam Jackson verified that 6 is the correct number of timings.

I don't have the docs for 1.2 or earlier, but we're > paranoid enough about not adding broken timings that we should be fine. This patch is basically a clean up, because timings[] is declared inside a union and increasing the number of elements here doesn't change the overall size of the union.
