From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxx>
Currently when one enables driver debugging dmesg gets spammed, at I
suspect vblank rate, with messages like:
[drm:amdgpu_dm_atomic_check [amdgpu]] MPO enablement requested on crtc:[00000000f073c3bb]
Fix if by converting some logging from deprecated and incorrect
DRM_DEBUG_DRIVER to drm_dbg_atomic. Plus some localized drive-by changes
to drm_dbg_kms.
By no means an exhaustive conversion but at least it allows turning on
driver debug selectively.
