Serious regression in 3.5's iTCO_wdt, does anyone care?

This regards the following commit in the Linus tree:

commit 887c8ec7219fc8eba78bb8f44a74c660934e9b98
Author: Aaron Sierra <asierra@xes-inc.com>
Date:   Fri Apr 20 14:14:11 2012 -0500

    watchdog: Convert iTCO_wdt driver to mfd model

Ever since the Linux 3.5 update, the iTCO_wdt driver has been completely
non-functional on every machine I encountered due to the above
conversion. A bug report for this problem has been open at
https://bugzilla.kernel.org/show_bug.cgi?id=44991 for over a month.

Yet, neither the author of the commit, nor the people who signed off on
it have reacted to the bug report.

At this point, I believe that none of you are actually aware of the
problem and I write you to change that unfortunate situation.

Regards
Thomas Bächler

And there I thought I had searched the LKML for lpc_ich and iTCO_wdt.
Apparently my last search was more than a week ago.

Would have been nice if you posted the link to the discussion into the
bug report, this would have saved me (and others) some trouble.

Thanks anyway, the discussion has all the information I needed. Sorry
for the noise.

Cc'ing the relevant maintainers usually helps...

I applied Feng's patch to my for-linus branch and I'll send a pull request
soon. It should be part of the 3.6 kernel.

Cheers,
Samuel.
