[PATCH] hwmon: (3/3) pc87360 driver update
pc87360: consolidate fan helper This patch consolidates the _set_fan_min() helper routine into the 2 line sysfs-callback wrapper that uses it. Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
