What should CREATE_BUFS do if count == 0?

Hi all, I'm extending v4l2-compliance with support for VIDIOC_REQBUFS and VIDIOC_CREATE_BUFS, and I ran into an undefined issue: what happens if VIDIOC_CREATE_BUFS is called with count set to 0? I think there should be a separate test for that. Right now queue_setup will receive a request for
