| Subject: iio: improve IIO_CONCENTRATION channel type description |
| |
| From: Tomasz Duszynski <tomasz.duszynski@octakon.com> |
| |
| [ Upstream commit df16c33a4028159d1ba8a7061c9fa950b58d1a61 ] |
| |
| IIO_CONCENTRATION together with INFO_RAW specifier is used for reporting |
| raw concentrations of pollutants. Raw value should be meaningless |
| before being properly scaled. Because of that description shouldn't |
| mention raw value unit whatsoever. |
| |
| Fix this by rephrasing existing description so it follows conventions |
| used throughout IIO ABI docs. |
