sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. Use sysfs_emit() to format the custom `in_power_shunt_resistor` and `in_current_shunt_resistor` device attributes of the max9611 driver.
