Huh? Something evils seems to be going on in V4L2 land. I've spotted the following lines in videobuf-core.c:videobuf_reqbufs
req->count = retval;done: mutex_unlock(&q->vb_lock); return retval;
That would explain the retval '2'. It seems a retval = 0; statement is missing here for the success case.
Indeed, so iow I'm happy to conclude that thie is not a libv4l bug :)
