From 0df6454da937548594774788b009616ed27607ed Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 28 Oct 2010 20:31:51 +0200 Subject: hwmon: (it87) Move conversion functions Move conversion functions until after structure defintions. This is needed for future changes which make use of the structures in the conversion funtcions.
