+
+The *outfile passed to parse_input_files can only be either set to
+optarg or be NULL. optarg should not be free'd and NULL does not need
+to.
+
+Since we no longer use on_exit to unlink outfile we also don't need to
+set *outfile to NULL.

-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.

-If <endian.h> does not provide these macros, use our own.
-
-This fixes issue #84.
