Instead of adding a completion for each request and using only the
last one, maybe we can do this instead here:
while ((req = virtqueue_get_buf(vq, &len))) {
if (req->out_hdr.flags == cpu_to_le32(VIRTIO_I2C_FLAGS_FAIL_NEXT))
Is this for the last one check ? For the last one, this bit should be
cleared, right ?
complete(&vi->completion);
}
Since we already know which is the last one, we can also check at this
point if buffers for all other requests are received or not.
