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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
