Frank Li b266e0d4da i3c: master: Fix missing 'ret' assignment in set_speed()
Fix a probe failure in the i3c master driver that occurs when no i3c
devices are connected to the bus.

The issue arises in `i3c_master_bus_init()` where the `ret` value is not
updated after calling `master->ops->set_speed()`. If no devices are
present, `ret` remains set to `I3C_ERROR_M2`, causing the code to
incorrectly proceed to `err_bus_cleanup`.

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.
