[PATCH] hwmon: Fix for first generation Abit uGuru chips
Now that the abituguru driver is seeing some more widespread testing it has turned out that one the first generation of Abit uGuru motherboards, with uGuru revision 1, the autodetect bank1 sensor type code doesn't (always) work. This patch adds a module param to override the autodetect, and it adds validity checks for the value of the 2 other autodetection override module params. An example of howto use the new param can be found here: http://lm-sensors.org/wiki/Configurations/Abit/AN7 Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
