[PATCH 4.20 048/127] drm/amdgpu: Reorder uvd ring init before uvd resume

From: Greg Kroah-Hartman
Date: Thu Jan 24 2019 - 14:50:19 EST

4.20-stable review patch. If anyone has any objections, please let me know.

------------------

[ Upstream commit 3b34c14fd50c302db091f020f26dd00ede902c80 ]

As amd_uvd_resume() accesses the uvd ring, it must be initialised first
or else we trigger errors like:
