Daniel Mentz cd268264f5 scsi: ufs: core: Leave space for '\0' in utf8 desc string
[ Upstream commit a75a16c62a2540f11eeae4f2b50e95deefb652ea ]

utf16s_to_utf8s does not NULL terminate the output string. For us to be
able to add a NULL character when utf16s_to_utf8s returns, we need to make
sure that there is space for such NULL character at the end of the output
buffer. We can achieve this by passing an output buffer size to
utf16s_to_utf8s that is one character less than what we allocated.

Other call sites of utf16s_to_utf8s appear to be using the same technique
where they artificially reduce the buffer size by one to leave space for a
NULL character or line feed character.

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.
