[PATCH 13/13] iio: sps30: Use 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 `cleaning_period` device attribute of
the sps30 driver.
