From 24cb4f3126971e1350a619af715bfc3ee43cc224 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 30 Oct 2020 15:32:09 +0000 Subject: [PATCH] drm/i915: Reduce severity for fixing up mistaken VBT tc->legacy_port If the VBT assigned tc->legacy_port mismatches the live_status indicator for the connector, we ignore the VBT directive and switch over to the HW setting. This is not a driver error, unless we happen to misparse the VBT or the live_status registers. However, for the system in CI where the error is only reported on 1 port out of 4, the evidence indicates the VBT is wrong. Stop flaging this as an error since the cause is beyond our control, fixup the mistake and continue on.
