[BISECTED] New kernel warning on v5.10-rc1

[Tom Seewald]

Upstream commit 6d90a208cfff ("drm/amd/display: Move disable interrupt
into commit tail") has introduced the following kernel warning on my
system with a RX 560 (Polaris 11) GPU. The warning is printed
immediately after I login.

amdgpu 0000:01:00.0: drm_WARN_ON_ONCE(drm_drv_uses_atomic_modeset(dev))
WARNING: CPU: 1 PID: 972 at drivers/gpu/drm/drm_vblank.c:722
drm_crtc_vblank_helper_get_vblank_timestamp_internal+0x31b/0x330 [drm]

I have confirmed that reverting this commit causes the warning to no
longer appear. See the gitlab bug report [1] for the bisect log and
full backtrace. Please cc me in your replies as I am not subscribed to
the amd-gfx mailing list.
