New devices (e.g. LIS2DW12) enable all axis by default and do not export that capability in register map. Check if the enable_axis register address has been declared in st_sensor_settings map in order to verify if the driver needs to enable all sensor axis Signed-off-by: Lorenzo Bianconi <redacted> --- drivers/iio/common/st_sensors/st_sensors_core.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
