[PATCH 07/13] iio: lm3533: 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 device attributes of the lm3533
driver.
