From e0b1ef58d98ae0feba98190c9faf192aabceb811 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Thu, 23 Mar 2023 16:20:21 +0200 Subject: [PATCH] drm/i915/tc: Check TC mode instead of the VBT legacy flag After the previous patch the TC mode in the connect/disconnect functions is always in sync with the VBT legacy port flag, so for consistency with the rest of the function check the TC mode instead of the VBT flag.
