From 7f69fb033b38022554fc43f991aef030021b2d91 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Mon, 12 Jan 2015 14:32:02 +0100 Subject: i8k: Make fan module parameters an unsigned MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Setting negative fan multiplier or maximal fan speed does make any sense and can cause problems. So ensure that negative values will not be accepted.
