Sorry, I didnt follow the STANDARDS last time I send this patch.
As you can see, its for the 2.6.17.3 kernel driver w83627hf.c
From: Carlos Olalla <com.ea at tinet.org>
filename=hwmon-w83627hf-add-pwm-support.patch
This patch adds support for pwm clock selection and pwm clock scaling
for the w83627hf and the w83697hf hardware monitors, both supported by this driver.
