The I2C Address Translator (ATR) module defines mappings from i2c_client structs to aliases. However, only the physical address of each i2c_client struct is actually relevant to the workings of the ATR module. Moreover, some drivers require address translation functionality but do not allocate i2c_client structs, accessing the adapter directly instead. The SFP subsystem is an example of this. Replace the "i2c_client" field of the i2c_atr_alias_pair struct with a u16 "addr" field. Rewrite helper functions and callbacks as needed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
