From 39ac7268c4350040976005da98daf10edf676d3e Mon Sep 17 00:00:00 2001
From: Stephan Hoffmann <sho@relinux.de>

Subject: [PATCH] Fix conflicting round() function

calibrator.c defines a local round() function that conflicts
with the one from the standard library.

This is fixed by renaming the local function.
