From a3200debde5fda3e25f7e22cb2bc17a9280f7811 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 6 Sep 2019 10:46:14 +0300 Subject: drm/modes: Make the whitelist more const The commit 3764137906a5 ("drm/modes: Introduce a whitelist for the named modes") introduced a whitelist in the named modes lookup code in order to be a bit more robust. However, even though the char pointers were made const, the array itself was not. Let's fix that.
