From 8f1b7eb11422d28fbc7432f0dee2f97aead09417 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 22 Oct 2012 12:15:00 +0100 Subject: iio: Do not accept multiple '.' in fixed point numbers Currently when parsing a fix-point number we silently skip any additional '.' found in the string. E.g. '1.2.3.4' gets parsed as '1.234'. This patch disallows this and returns an error if more than one '.' is encountered.
