From 49979d091d1847823c064301da1ec173619ddd92 Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Fri, 1 Jul 2011 11:34:26 +0200 Subject: asus-wmi: fix hwmon/pwm1 The code was completly broken, and should never had been sent to the kernel. That's what happens when you write code without hardware to test it.
