Subject: [PATCH v2 5/9] drm/sun4i: dsi: Fix front vs back porch calculation
Date: Fri, 8 Feb 2019 10:53:18 +0100 [thread overview]
Message-ID: <90c2375b8a853cae0dcc135cedb47edbc26168d8.1549619502.git-series.maxime.ripard@bootlin.com> (raw)
In-Reply-To: <cover.23dbbc9b943ff8f36253ac7c617e2eda142b1b69.1549619502.git-series.maxime.ripard@bootlin.com>
Since I always confuse the back and front porches, a few miscalculation
slipped through. Fix them.
