In function 'fan53555_device_setup', a call to 'regmap_update_bits' is made with the mode_mask variable potentially uninitialized.
This can be the case if di->vendor is FAN53526_VENDOR_FAIRCHILD and di->sleep_vsel_id is not handled by the case (neither FAN53555_VSEL_ID_0 nor FAN53555_VSEL_ID_1). I am not sure how likely it is to happen.
