From 4b65b884133f7a22bf99f150c0513d2a77e444b9 Mon Sep 17 00:00:00 2001 From: Francois Buergisser Date: Tue, 29 Oct 2019 02:24:47 +0100 Subject: [PATCH] media: hantro: Fix motion vectors usage condition commit 658f9d9921d7e76af03f689b5f0ffde042b8bf5b upstream. The setting of the motion vectors usage and the setting of motion vectors address are currently done under different conditions. When decoding pre-recorded videos, this results of leaving the motion vectors address unset, resulting in faulty memory accesses. Fix it by using the same condition everywhere, which matches the profiles that support motion vectors.
