From: Vasileios Amoiridis <vassilisamir@xxxxxxxxx> commit ae1f7b93b52095be6776d0f34957b4f35dda44d9 upstream. 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.
