Alexander Usyskin f1cb33a828 mei: trace: treat reg parameter as string 
commit 06d5a7afe1 upstream.

The commit
afd2627f72 ("tracing: Check "%s" dereference via the field and not the TP_printk format")
forbids to emit event with a plain char* without a wrapper.

The reg parameter always passed as static string and wrapper
is not strictly required, contrary to dev parameter.
Use the string wrapper anyway to check sanity of the reg parameters,
store it value independently and prevent internal kernel data leaks.

Since some code refactoring has taken place, explicit backporting may
be needed for kernels older than 6.10.

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 reStructuredText 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.
