Commit31b9887c72("i3c: remove i2c board info from i2c_dev_desc") removed the boardinfo from i2c_dev_desc to decouple device enumeration from setup but did not correctly lookup the i2c_dev_desc to store the new device, instead dereferencing an uninitialized variable. Lookup the device that has already been registered by address to store the i2c client device.

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.
