sensor_inst->fields.\n\nCreate the field attributes before exposing the enable_sensor sysfs\nattribute, so enable_sensor cannot be accessed before the state it\ndepends on has been initialized.\n\nOn remove, delete enable_sensor before freeing the field attributes,\nso a concurrent sysfs write cannot dereference freed memory through\npower_state or
