From 2251cf1a4b37bd483501614c2d78f5b8286f20d7 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 4 Sep 2005 22:52:17 +0200 Subject: [PATCH] [PATCH] hwmon: w83627hf: no reset by default Make the reset of the chips in w83627hf optional rather than the default. This reset has been causing trouble several times already. It may even go completely away unless it proves to be useful to at least one user.
