Hi Jean, MDS
This is Chunhao. The following is my answer.

Yeah, I agree with you, I will persuade my manager to commit the 792
driver as soon as possible. :-)
But since my manager is taking the Chinese traditional new year vacation
from this morning, I can NOT contact him for about 10 days. And my
vacation also will start two days later.:-)
We will back to work at Feb. 16. At that time I will contact you about
it. Is that OKay?

Do you mean that the patch to libsensors should be provided by me?
Or MDS will write it?
Besides w83792d.c, I also have finished the following files:
I attached them in this email, please check them. it is for my
test. You may refer to them so that you can know the work I have done.
But I do NOT modify the /etc/sensors.conf because I'm not very familiar
with it, maybe MDS can modify it for me ;-)
Could you confirm that if I commit the 792 driver, which files should I

OK, I see, thanks, I will pay more attention to
at first, especially to the "PWM" section. Then I will contact you if I
more questions about it. :-)
