[PATCH] hwmon: Add support for the Winbond W83687THF
Add support for the Winbond W83687THF chip to the w83627hf hardware monitoring driver. This new chip is almost similar to the already supported W83627THF chip, except for VID and a few other minor changes. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
