From 8ca136741e15e8546e787ae92a7f4aeca84be494 Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Sat, 18 Oct 2008 20:27:34 -0700 Subject: hwmon/pc87360 separate alarm files: add dev_dbg help temp and vin status register values may be set by chip specifications, set again by bios, or by this previously loaded driver. Debug output nicely displays modprobe init=\d actions. Signed-off-by: Jim Cromie Cc: Jean Delvare Cc: "Mark M.
