From 3d289d2578eff2a274fc5e63fca2a611404a3003 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Tue, 16 Jun 2020 17:18:53 +0300 Subject: drm/i915/dp_mst: Clear only the ACT sent flag from DP_TP_STATUS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's not clear if the DP_TP_STATUS flags other than the ACT sent flag have some side-effect, so don't clear those; we don't depend on the state of these flags anyway.
