iio: ina2xx-adc: sysfs_emit()
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_allow_async_readout` device attribute of the ina2xx-adc driver.
