From 1cf0abb6c983d90ec541ebba79934a9c4786df1d Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 25 Jun 2018 12:24:10 -0500 Subject: [PATCH] drm/amdgpu/sdma: simplify sdma instance setup MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Set the me instance in early init and use that rather than calculating the instance based on the ring pointer.
