[PATCH v1 00/17] iio: chemical: bme680: Driver cleanup

[Vasileios Amoiridis]

This started as a series to add support for buffers and the new
BME688 but it ended up being just a cleaning series. These might
be quite some patches for such a thing but I feel that they are
are well split, in order to allow for better review.

The patches are mostly small changes but essential for the correct use
of the driver. The first patches looked like fixes that should be
marked for the stable. Patches [11,17/17] might be a bit bigger but 11/17
is quite straightforward and 17/17 is basically a duplication of a
very similar commit coming from the BMP280 driver [1].

In general, the datasheet [2] of the driver is not very descriptive,
and it redirects the user to the BME68x Sensor API [3]. All the things
that were identified from the BME68x Sensor API have been marked with
links to the original locations of the GitHub code. If this is too much
and we don't want this type of information on the commit message, please
let me know and I will fix it.
