From 5d4af988f39052b77f8fdd9ed5cb61ca1645a3a6 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 25 Jun 2018 12:41:21 -0500 Subject: [PATCH] drm/amdgpu/vce: simplify vce instance setup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Set the me instance in early init and use that rather than calculating the instance based on the ring pointer.
