The description of those vars produce this warning: Documentation/ABI/testing/sysfs-bus-iio:799: WARNING: Inline emphasis start-string without end-string. Due to an asterisk, which is the markup for emphasis. One possible fix would be to use ``*_timeout`` to avoid it, but looking at the descriptions of other fields in this file, a common pattern is to refer to "these" when talking about the API calls that are described. So, change the text in order to preserve the meaning while avoiding the need of using an asterisk there.
