commit a6616bc9a0af7c65c0b0856a7508870a4a40c4ac upstream.
The commit ba8f6f4ae254 ("iwlwifi: dbg: add dumping special device
memory") added a termination of name string just to be sure, and this
seems causing a regression, a GPF triggered at firmware loading.
Basically we shouldn't modify the firmware data that may be provided
as read-only.
This patch drops the code that caused the regression and keep the tlv
data as is.

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.
