This header is already part of the kernel headers, so it should already
be part of the toolchain. Do you have a specific case where this header
is missing?

This is a different header than the kernel one, although confusingly named 
identically. On my Debian system the libi2c-dev package provides i2c-dev.h, 
and diverts the kernel header to i2c-dev.h.kernel.

$ dpkg -S /usr/include/linux/i2c-dev.h
diversion by libi2c-dev from: /usr/include/linux/i2c-dev.h
diversion by libi2c-dev to: /usr/include/linux/i2c-dev.h.kernel
linux-libc-dev:amd64, libi2c-dev: /usr/include/linux/i2c-dev.h

The contents of the header are different, the one from i2c-tools 
contains more.

We also carry a patch similar to this. Our patch has an addition which 
is a dependency on linux (assuming it is selected in the config). This 
ensures that the header from the kernel gets over ridden by the one from 
i2c-tools and not the other way around.

Regards
Will

Yes. In the kernel documentation (Documentation/i2c/dev-interface) it is explained as follows:

"So let's say you want to access an i2c adapter from a C program. The
first thing to do is "#include <linux/i2c-dev.h>". Please note that
there are two files named "i2c-dev.h" out there, one is distributed
with the Linux kernel and is meant to be included from kernel
driver code, the other one is distributed with i2c-tools and is
meant to be included from user-space programs. You obviously want
the second one here."

Makes sense. Could this patch be mainlined, instead of what I sent?

In fact, I will revert it: the modified i2c-dev.h by the i2c-tools
has some definitions that conflicts with the i2c.h normally provided by
the kernel headers. Therefore, if a userspace program or library
includes both, it fails to build. This is the case with libsoc, see
http://autobuild.buildroot.org/results/1f4/1f451a338487a2a3c8a8f9b18540d41b90ee5aac/build-end.log:

Apparently, it is well-known to the i2c-tools developers that their
i2c-dev.h is broken, and not really usable in practice.
