Lorenzo Bianconi d1f13dcad5 iio: st_sensors: add register mask for status register ... [ Upstream commit e72a060151 ] Introduce register mask for data-ready status register since pressure sensors (e.g. LPS22HB) export just two channels (BIT(0) and BIT(1)) and BIT(2) is marked reserved while in st_sensors_new_samples_available() value read from status register is masked using 0x7. Moreover do not mask status register using active_scan_mask since now status value is properly masked and if the result is not zero the interrupt has to be consumed by the driver. This fix an issue on LPS25H and LPS331AP where channel definition is swapped respect to status register. Furthermore that change allows to properly support new devices (e.g LIS2DW12) that report just ZYXDA (data-ready) field in status register to figure out if the interrupt has been generated by the device.
