+Subject: [PATCH] tpm2_certify: fix "'type' may be used uninitialized" warning
+
+get_key_type does not assign a value to 'type' on error conditions,
+which makes the compiler believe that it will be used uninitialized in
+the LOG_ERR call, in set_scheme. In practice this will never happen
+because set_scheme returns immediately if get_key_type retuns false but
+the compiler does not understand that logic and fails because warnings
+are treated as errors.
+
+Adapted for version 3.0.3 from the change submitted upstream:

+ https://github.com/tpm2-software/tpm2-tools/pull/954
