Wenwen Wang 7afe9a4e56 i3c: master: fix a memory leak bug
In i3c_master_getmwl_locked(), the buffer used for the dest payload data is
allocated using kzalloc() in i3c_ccc_cmd_dest_init(). Later on, the length
of the dest payload data is checked against 'sizeof(*mwl)'. If they are not
equal, -EIO is returned to indicate the error. However, the allocated
buffer is not deallocated on this path, leading to a memory leak.

To fix the above issue, free the buffer before returning the error.

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.
