From 6722feada7f6213ba06d510ef853e57ddcd59dae Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 7 Oct 2007 12:25:46 +0200 Subject: hwmon: (lm78/w83781d) Probe fewer I2C addresses We've never seen any device supported by the lm78 or w83781d driver at addresses 0x20-0x27, so let's stop probing these addresses. Extra probes cost time, and have potential for confusing or misdetecting other I2C devices. Signed-off-by: Jean Delvare Signed-off-by: Mark M.
