From 6cf0a91ebe11cee1df871619af4eb58c9af32666 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 4 Apr 2014 18:01:34 +0200 Subject: hwmon: Avoid initializing the same field twice All hwmon drivers allocate their data structure with some form of kzalloc, so setting data fields to zero explicitly is a waste of time.
