From c5e3fbf22ccba0879b174fab7ec0e322b1266c2c Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 18 Jan 2006 22:39:48 +0100 Subject: [PATCH] hwmon: Fix reboot on it87 driver load Only scan I2C address 0x2d. This is the default address and no IT87xxF chip was ever seen on I2C at a different address. These chips are better accessed through their ISA interface anyway. This fixes bug #5889, although it doesn't address the whole class of problems. We'd need the ability to blacklist arbitrary I2C addresses on systems known to contain I2C devices which behave badly when probed. Plan the I2C interface for removal as well. If nobody complains within a year, it will confirm my impression that the I2C interface isn't actually needed by anyone.
