A previous patch addressed a fortified-memcpy warning on older compilers,
but there is still a warning on gcc-14 in some configurations:
In file included from include/linux/string.h:390,
from drivers/net/wireless/ath/ath12k/wow.c:7:
drivers/net/wireless/ath/ath12k/wow.c: In function 'ath12k_wow_convert_8023_to_80211.isra':
include/linux/fortify-string.h:114:33: error: '__builtin_memcpy' accessing 18446744073709551610 or more bytes at offsets 0 and 0 overlaps 9223372036854775797 bytes at offset -9223372036854775803 [-Werror=restrict]

drivers/net/wireless/ath/ath12k/wow.c:199:25: note: in expansion of macro 'memcpy'

Address this the same way as the other two, using size_add().

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.
