+Subject: [PATCH] dp.h: make format_guid() handle misaligned guid pointers
+ safely.
+
+GCC 9 adds -Werror=address-of-packed-member, which causes us to see the
+build error reported at
+ https://bugzilla.opensuse.org/show_bug.cgi?id=1120862 .
+
+That bug report shows us the following:
+
+In file included from dp.c:26:
+dp.h: In function 'format_vendor_helper':
+dp.h:120:37: error: taking address of packed member of 'struct <anonymous>' may result in an unaligned pointer value [-Werror=address-of-packed-member]
+  120 |  format_guid(buf, size, off, label, &dp->hw_vendor.vendor_guid);
+      |                                     ^~~~~~~~~~~~~~~~~~~~~~~~~~
+dp.h:74:25: note: in definition of macro 'format_guid'
+   74 |   _rc = efi_guid_to_str(guid, &_guidstr);   \
+      |                         ^~~~
+cc1: all warnings being treated as errors
+
+This patch makes format_guid() use a local variable as a bounce buffer
+in the case that the guid we're passed is aligned as chaotic neutral.
+
+Note that this only fixes this instance and there may be others that bz
+didn't show because it exited too soon, and I don't have a gcc 9 build
+in front of me right now.
