From: Oleksandr Kravchenko <o.v.kravchenko@xxxxxxxxxxxxxxx> This patch fixes the issue with double minus in output when reading channels from sysfs for IIO_VAL_INT_PLUS_MICRO and IIO_VAL_INT_PLUS_NANO cases. Until this patch if val and val2 both are negatives output string contains "--" before digits. It is result of "-%d..." in sprintf() format.
