From 17003d109e6cd08d4db5f6525a1023537ce6c743 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 23 Feb 2022 12:09:23 +0000 Subject: [PATCH] drm/i915: make a handful of read-only arrays static const MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Don't populate the read-only arrays on the stack but instead make them static const and signed 8 bit ints. Also makes the object code a little smaller. Reformat the statements to clear up checkpatch warning.
