iio: magnetometer: st_magn: fix drdy line configuration for LIS3MDL
Data-ready line in LIS3MDL is routed to drdy pin and it is not possible to select a different INT pin. st_sensors_set_dataready_irq() assumes that if drdy int address is not exported in register map, irq trigger is not supported by the sensor and hw_irq_trigger is always false. Based on this configuration st_sensors_irq_thread does not consume generated interrupt causing an unhandled irq. Fix this taking into account status register address in st_sensors_set_dataready_irq() Fixes: 90efe055 (iio: st_sensors: harden interrupt handling) Signed-off-by: NLorenzo Bianconi <lorenzo.bianconi@st.com> Cc: <Stable@vger.kernel.org> Signed-off-by: NJonathan Cameron <Jonathan.Cameron@huawei.com>
