Subject: [PATCH] media: sun8i-di: Fix chroma difference threshold
[ Upstream commit 856525e8db272b0ce6d9c6e6c2eeb97892b485a6 ]
While there is no good explanation what this value does, vendor driver
uses value 31 for it. Align driver with it.
Fixes: a4260ea49547 ("media: sun4i: Add H3 deinterlace driver")
