Subject: iio: ABI: Clarify proximity output value

From: Daniel Baluta <[email protected]>

commit bdc10d57f236b534fb675a4bbefd10017aeb2b26 upstream.

Current description for proximity measurement is ambiguous. While the first part says that proximity is measured by observing reflectivity, the second part incorrectly infers that reported values should behave like a distance.

This is because of AS3935 lightning sensor which uses the proximity API, while not being a true proximity sensor.

Note this is marked for stable as it accompanies a fix in ABI usage to the sx9500 driver which would otherwise appear to be correct.
