+Subject: [PATCH] Fix assignment of an enumerator of a different type
+
+The kVSFSysStrOpenUnknown enumerator is not part of the
+EVSFSysUtilOpenMode enum. The assignment causes a build failure with
+gcc 10.
+
+The open_mode variable need not be initialized, because the switch
+statement either sets the variable or causes us to exit.
+
+Resolves: rhbz#1800239
