Hi Connie,

My series of fixes for vfio-ccw depends on this patch as I would like to 
call cp_free unconditionally :) (I had developed my code on top of your 
patches).

Could we pick this patch up as well when/if you pick up my patch series? 
I am in the process of sending out a v2.

Regarding this patch we could merge it as a stand alone patch, separate 
from this series. And also the patch LGTM
