[PATCH AUTOSEL 4.19 8/9] drm/imx: only send event on crtc disable if kept disabled

[Sasha Levin]

From: Robert Beckett <bob.beckett at collabora.com>

[ Upstream commit 5aeab2bfc9ffa72d3ca73416635cb3785dfc076f ]

The event will be sent as part of the vblank enable during the modeset
if the crtc is not being kept disabled.

Fixes: 5f2f911578fb ("drm/imx: atomic phase 3 step 1: Use atomic configuration")
