The WARN is new, the problem is old.

commit c543188afb7a83e66161c026dc6fd5eb38dc0b63
Author: Paulo Zanoni <paulo.r.zanoni@...el.com>
Date:   Tue May 15 18:09:02 2012 -0300

    drm: add generic ioctls to get/set properties on any object
    
    Useless for connector properties (since they already have their own
    ioctls), but useful when we add properties to CRTCs, planes and other
    objects.

Before that commit we had no idea that we had run out of property slots.
I think the WARN is genuine, but maybe we should just bump the count set
it to WARN_ONCE and hope the conversion to lists arrives sooner rather
than latter.
