Tom Rix 8654464086 i3c: master: dw: check return of dw_i3c_master_get_free_pos() 
[ Upstream commit 13462ba181 ]

Clang static analysis reports this problem
dw-i3c-master.c:799:9: warning: The result of the left shift is
  undefined because the left operand is negative
                      COMMAND_PORT_DEV_INDEX(pos) |
                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~

pos can be negative because dw_i3c_master_get_free_pos() can return an
error.  So check for an error.

README 

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.
