From e693810ce8495ce3e227dacaa83f501b3b8ab204 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 13 Oct 2006 16:56:28 +0200 Subject: hwmon: Let w83781d and lm78 load again Let the w83781d and lm78 hardware monitoring drivers load even when no chip was detected at the ISA address. There can still be supported chips connected to an I2C bus or SMBus. This fixes bug #7293.
