This will conflit with "drm/vkms: Switch to dynamic allocation
for CRTC" [1], where you switched to DRM_DEV_ERROR.
No proferences about the log function, just a heads up so when
you rebase one of the patches we keep logging consistent.

I did not check if my series had conflict between them, so I'm not
surprised. I will change it to the DEV variant and send a v2, espicially
since Leo [1] wants to work to clean the logging in VKMS :-)
