I think that was the original post. (sorry should have added references!)

Yes, that's why he was advised to combine it with your driver leading
via about 3 revisions
to
http://lists.lm-sensors.org/pipermail/lm-sensors/2009-October/026840.html
(removed a few pointless headers from previous version
http://lists.lm-sensors.org/pipermail/lm-sensors/2009-September/026706.html
.)


which at first glance is pretty much the same as Samu's driver.
(hence real issue with overlapping work).

I do wonder if it is worth adding a mailing list entry to the driver
MAINTAINERS
entry (unless lm-sensors is where you do want anything relevant to be
discussed?).
Problem here is this evolved in a thread not initially related to your
driver and hence I guess no one noticed you weren't cc'd when it became
relevant.

p.s. Kalhan, btw, just noticed a typo in the patch message :
Macroelectronics->Microelectronics.
