Subject: [PATCH] drm: sun4i: hdmi: Fix inverted HPD result
Date: Sat, 11 Jul 2020 09:10:30 +0800 [thread overview]
Message-ID: <20200711011030.21997-1-wens@kernel.org> (raw)
From: Chen-Yu Tsai <wens@csie.org>
When the extra HPD polling in sun4i_hdmi was removed, the result of
HPD was accidentally inverted.
Fix this by inverting the check.
Fixes: bda8eaa6dee7 ("drm: sun4i: hdmi: Remove extra HPD polling")
Signed-off-by: Chen-Yu Tsai <wens@csie.org>

Sorry for the screw-up.
