Not a totally clear cut case given there are only two instances, but
I think, on balance that it is an improvement.

As this isn't really connected to patch 1 in the series (or the fix
going via the other tree) I'll apply this one now. Please only
send a new version of patch 1.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders (0-day etc) to see if they can find anything
we have missed.

Some time after those test results have come in, I'll push the tree
out as togreg, and in a few weeks send a pull request to Greg to
hopefully have it pulled into his tree which is part of Linux next
and from which he will then send a pull request to Linus in the
next merge window.

Thanks,

Jonathan
