Subject: [PATCH] MokManager: avoid -Werror=address-of-packed-member
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When compiling with GCC 9, there are a couple of errors of the form
MokManager.c: In function ‘write_back_mok_list’:
MokManager.c:1056:19: error: taking address of packed member of ‘struct <anonymous>’ may result in an unaligned pointer value [-Werror=address-of-packed-member]
1056 | if (CompareGuid(&(list[i].Type), &X509_GUID) == 0)
| ^~~~~~~~~~~~~~~
Copying the member of the packed struct to a temporary variable and
pointing to that variable solves the problem.
