One comment inline. I added a fixes tag but also a note saying I would
not suggest backporting to stable.

There are too many things wrong with this driver for any backports
to really be worthwhile. It didn't work at all for i2c until last cycle
for example!

This looks to be called LDAC not LDCA?

Different error so I don't mind that being fixed later!
