[PATCH v2 0/3] staging: iio: replace sprintf() with sysfs_emit()

[Gabriel Rondon]

Replace the remaining sprintf() calls with sysfs_emit() in sysfs
show functions across three staging IIO drivers: ad7816, ad5933, and
ad9834.

sysfs_emit() is the preferred API for sysfs callbacks as it is aware
of the PAGE_SIZE buffer limit. Build tested with gcc 13.3.

Changes since v1:
- ad5933: remove unnecessary (int) cast in ad5933_show_frequency()
  and use %llu format specifier for unsigned long long (Andy Shevchenko)
- ad9834: simplify wavetype_available show functions by removing
  intermediate string variable and returning directly (Andy Shevchenko)

Gabriel Rondon (3):
  staging: iio: ad7816: use sysfs_emit() in show functions
  staging: iio: ad5933: use sysfs_emit() in show functions
  staging: iio: ad9834: use sysfs_emit() and simplify show functions
