I'm going to apply these the 'slow' route as the failure case in
patch 2 is reasonably uncommon.  Maarten if you want to request
a back port to stable after these have merged (will probably
be a while given where we are in the cycle) then that's fine
with me.

Applied to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.

Thanks,

Jonathan
