Bean Huo cd2898f0fd scsi: ufs: core: fix incorrect buffer duplication in ufshcd_read_string_desc() 
[ Upstream commit d794b499f9 ]

The function ufshcd_read_string_desc() was duplicating memory starting
from the beginning of struct uc_string_id, which included the length and
type fields. As a result, the allocated buffer contained unwanted
metadata in addition to the string itself.

The correct behavior is to duplicate only the Unicode character array in
the structure. Update the code so that only the actual string content is
copied into the new buffer.

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.
