+Subject: [PATCH] fix unaligned point value with GCC9
+
+Follow those steps:
+  osc build
+
+and occurs error:taking address of packed member of 'struct <anonymous>' may result in an unaligned point value [-Werror=address-of-packed-member]
+
+This is because warning [-Werror=address-of-packed-member] is dealing with error in gcc9
+
+Fix MokManager.c code to deal with this issue
