Yup, this one needs the previous one, both pushed to drm-misc-next.

Aishwarya, while reviewing your patches I've noticed that you've missed to
case of drm_dev_unref() in the drm core code, one in drm_pci.c and one in
drm_prime.c. Can you pls do a follow-up patch to address these two? Fixing
up the core completely is nice, drivers can be done later on (also by
others, this is a prefect newbies tasks). But making sure the core is
consistent is good I think.
