Subject: [PATCH 13/14] drm/amdgpu/ring: move debugfs init into core amdgpu debugfs
Date: Tue,  4 Feb 2020 22:48:51 -0500	[thread overview]
Message-ID: <20200205034852.4157-14-alexander.deucher@amd.com> (raw)
In-Reply-To: <20200205034852.4157-1-alexander.deucher@amd.com>

In order to remove the load and unload drm callbacks,
we need to reorder the init sequence to move all the drm
debugfs file handling.  Do this for rings.
