From 95d4fdfab82ee0cefa30a83a720ed28864c18878 Mon Sep 17 00:00:00 2001
From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
Date: Tue, 15 Jan 2019 10:33:58 -0500
Subject: [PATCH 0810/2940] drm/amd/display: Re-enable CRC capture following
modeset
[Why]
During any modeset the CRTC stream is removed and a new stream is added.
This new stream doesn't carry over CRC capture state if it was
previously set.
[How]
Re-program the stream for CRC capture. The existing DRM callback can
be re-used here for the most part - the only modification needed is
additional locking now that it's called from within commit tail.
