[ Upstream commiteb11c3bb64] Device has up to WSA881X_MAX_SWR_PORTS number of ports and the array assigned to prop.sink_dpn_prop has 0..WSA881X_MAX_SWR_PORTS-1 elements. On the other hand, GENMASK(high, low) creates an inclusive mask between <high, low>, so we need the mask from 0 up to WSA881X_MAX_SWR_PORTS-1. Theoretically, too wide mask could cause an out of bounds read in sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy driver, e.g. adding incorrect number of ports via sdw_stream_add_slave().

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.
