[PATCH v1 01/17] iio: chemical: bme680: Fix pressure value output

From: Vasileios Amoiridis
Date: Mon May 27 2024 - 14:38:30 EST


The IIO standard units are measured in kPa while the driver
is using hPa.

Apart from checking the userspace value itself, it is mentioned also
in the Bosch API [1] that the pressure value is in Pascal.
