From e0912e15d3e3b4f65deb8e53d060b1a49236adb2 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Thu, 8 Apr 2021 12:21:47 -0400 Subject: [PATCH] drm/amd/display: Always poll for rxstatus in authenticate [Why] Requirement from the spec - we shouldn't be potentially exiting out early based on encryption status. [How] Drop the calls from HDCP1 and HDCP2 execution that exit out early based on link encryption status.
