+Subject: libbpf: Fix uninitialized warning in btf_dump_dump_type_data
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: David Michael <fedora.dm0@gmail.com>
+
+commit dfd0afbf151d85411b371e841f62b81ee5d1ca54 upstream.
+
+GCC 11.3.0 fails to compile btf_dump.c due to the following error,
+which seems to originate in btf_dump_struct_data where the returned
+value would be uninitialized if btf_vlen returns zero.
+
+btf_dump.c: In function ‘btf_dump_dump_type_data’:
+btf_dump.c:2363:12: error: ‘err’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
+ 2363 |         if (err < 0)
+      |            ^
+
+Fixes: 920d16af9b42 ("libbpf: BTF dumper support for typed data")
