IIO_DEVICE_ATTR_NAMED is a macro, as indicated by the > capital letters, and you have to look and see what the code expands into. Technically it is a subtraction, but the symbol rather than the c operator ;) It's indicating that this sysfs attribute is referring to any voltage channels minus other voltage channels (differential channels). Sometimes I wonder if we should leave this there for ever as a way of getting people to understand that they need to look really closely at what checkpatch is suggesting and not assume it is right.
