Oh, I didn't notice that. Nice then.

I see from the git logs that this and some other related patches have
been added now. Another question I have then is about the name: to me 
spi_non_blocking_transfer() sounds like it would do the opposite of
what I guess it does - it would go ahead without blocking on the call.

I guess what the name means is that it will not sleep during the call,
but for pushing it upstream, could it be better to name it something
else? Perhaps spi_sync and then rename the existing API name (which I
think is more than a bit strange), or maybe spi_sync_nowait or
something?
