Kishon Vijay Abraham I 7a360e546a phy: ti: Fix missing sentinel for clk_div_table commit `6d1e6bcb31` upstream. _get_table_maxdiv() tries to access "clk_div_table" array out of bound defined in phy-j721e-wiz.c. Add a sentinel entry to prevent the following global-out-of-bounds error reported by enabling KASAN.

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.
