Subject: drm/amdgpu/display: move debugfs init into core amdgpu debugfs (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: d090e7db5a2f19df1fe1bff251b872483e50b79b
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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 display.
v2: add config guard for DC
