Subject: [PATCH] drm/i915/display/psr: Disable DC3CO when the PSR2 is used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Due to the changed sequence of activating/deactivating DC3CO, disable
DC3CO until the changed dc3co activating/deactivating sequence is applied.
