[PATCH 06/13] iio: ina2xx-adc: sysfs_emit()

[Lars-Peter Clausen <lars@metafoo.de>]

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.
