This is a frequent minor comment in reviews, so start cleaning up
existing drivers in the hope we get fewer cases of cut and paste.
There are not kernel wide rules for these, but for IIO the style
that I prefer (and hence most common) is:
- Space after { and before }
- No comma after terminator { }
This may cause merge conflicts but they should be trivial to resolve
hence I have not broken this into per driver patches.
