[ Upstream commite3fb3d4418] In function ath10k_wow_convert_8023_to_80211(), it will do memcpy for the new->pattern, and currently the new->pattern and new->mask is same with the old, then the memcpy of new->pattern will also overwrite the old->pattern, because the header format of new->pattern is 802.11, its length is larger than the old->pattern which is 802.3. Then the operation of "Copy frame body" will copy a mistake value because the body memory has been overwrite when memcpy the new->pattern. Assign another empty value to new_pattern to avoid the overwrite issue.

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.
