From 75c65480ba7d56e2ee164057ce8ab879931a3978 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 24 Aug 2016 16:56:21 -0400 Subject: [PATCH] drm/amdgpu: track the number of vce rings MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Rather than using a hardcoded value. This allows different versions to expose more or less rings. No functional change.
