Just applied it on current master (80d9534a133da170cade150700407920450a9753)
and seems ok.
Sorry I did not test this sooner - this went to Gmane but not to my email.
If you have time, could you please write up a quick man page for this driver?
Also, there seem to be some missing symbols and include files:
http://buildbot.networkupstools.org/public/nut/waterfall?branch=asem_i2c
The problem is that linux/i2c-dev.h must come from libi2c-dev to define the
required functions. Same header is part of the kernel, but without required
functions. Changed the configure.ac check to look for the functions, not just
the header.
To build the driver you'll need libi2c-dev package (part of i2c-tools) on
debian.
Also removed the #include <config.h> as you suggested.
