From 01f0ce3e859619ea84104d668a87ace924bd12df Mon Sep 17 00:00:00 2001 From: John Harrison Date: Mon, 12 Sep 2022 18:09:29 -0700 Subject: [PATCH] drm/i915/guc: Fix release build bug in 'remove log size module parameters' A patch was merged to remove the GuC log size override module parameters. That patch was broken and caused kernel error messages on boot in non CONFIG_DEBUG_GUC|GEM builds: [ 12.085121] i915 0000:00:02.0: [drm] *ERROR* Zero GuC log crash dump size! [ 12.092035] i915 0000:00:02.0: [drm] *ERROR* Zero GuC log debug size! So fit it.
