Subject: wifi: use struct_group to copy addresses
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=7c422dc57e77e55402633b51bba276e4b12d7ee4;p=carl9170fw.git

wifi: use struct_group to copy addresses

We sometimes copy all the addresses from the 802.11 header
for the AAD, which may cause complaints from fortify checks.
Use struct_group() to avoid the compiler warnings/errors.
