Call trace dmesg
system Environment:
--------------------------
platform: BDW HSW ILK BYT
Kernel: (drm-intel-next-queued) 57e00b2e1b348b3855f4a3b681d583f8c9cf39fb
Bug detailed description:
-------------------------
CallTrace "WARNING: CPU: 0 PID: 1418 at drivers/gpu/drm/drm_modes.c:119
drm_mode_probed_add+0x27/0x41 [drm]()" and "WARNING: CPU: 0 PID: 1418 at
drivers/gpu/drm/drm_crtc_helper.c:131 " after booting.
these two calltrace occurs by the same patch.
The first bad point is 3ec0db819315c765b3c7bbf7e9dee2fe1f186f47

drm/doc: Integrate drm_modes.c kerneldoc
And clean it up so that there's no kerneldoc warnings. There's still a
lot to do with this one here.
