Parav Pandit 4cb8bdaebb IB/cm: Avoid a loop when device has 255 ports 
[ Upstream commit 131be26750 ]

When RDMA device has 255 ports, loop iterator i overflows.  Due to which
cm_add_one() port iterator loops infinitely.  Use core provided port
iterator to avoid the infinite loop.

Fixes: a977049dac ("[PATCH] IB: Add the kernel CM implementation")

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.
