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_filter_notch_center_frequency` and fault_ovuv` device attributes of the max31865 driver.
