The DRM has wrappers for these function due to it being used on other
OS'es (BSD mainly)
However I will accept that the drm_calloc function should now just
called the kernel kcalloc function and this could probably be moved to
an inline in drm_memory.h
I'll code up something and put it my queue..
Thanks,
Dave.
