Anssi Hannula 05519b8589 xhci: fix uninitialized string returned by xhci_decode_ctrl_ctx() 
xhci_decode_ctrl_ctx() returns the untouched buffer as-is if both "drop"
and "add" parameters are zero.

Fix the function to return an empty string in that case.

It was not immediately clear from the possible call chains whether this
issue is currently actually triggerable or not.

Note that before commit 4843b4b5ec ("xhci: fix even more unsafe memory
usage in xhci tracing") the result effect in the failure case was different
as a static buffer was used here, but the code still worked incorrectly.

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.
