We currently have some complicated code in sfp_probe() which gets the I2C bus depending on whether the sfp node is DT or ACPI, and we use completely separate lookup functions. This could do with being in a separate function to make the code more readable, so move it to a new function, sfp_i2c_get(). We can also use fwnode_find_reference() to lookup the I2C bus fwnode before then decending into fwnode-type specific parsing. A future cleanup would be to move the fwnode-type specific parsing into the i2c layer, which is where it really should be.

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 Restructured Text 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.
