Subject: [PATCH v6 30/30] drm/rockchip: psr: Remove flush by CRTC
From: Tomasz Figa <tfiga@...omium.org>
It is not used anymore after last changes and it was not even correct to
begin with as it assumed a 1:1 relation between a CRTC and encoder,
while in fact a CRTC can be attached to multiple encoders.
