[PATCH] Documentation/i2c: direct users to i2c-tools regarding i2c/smbus.h

[Sam Hansen]

The current examples reference i2c/smbus.h, which is the first reference
in Documentation/i2c/dev-interface to anything related to the i2c-tools
project.  This moves the existing reference to i2c-tools up into the
C-example, directing the user to the project's git repository.

Hi Sam,

Please don't include the same persons in To: and Cc:. It makes the
message delivered twice to them.

I'm fine with moving the pointer to i2c-tools up in the document.
However I find it unfortunate to remove the only reference to libi2c.
Typically, distributions will only include the tools in i2c-tools, and
they are not relevant in this case. The library will be in a separate
package (libi2c or similar), and the header file in yet another package
(libi2c-devel or similar.) Although the exact package names are
distribution specific, it would be convenient to hint the reader at
which packages he is supposed to install. You could also mention that
the C program must be compiled with -li2c.
