This is new code. The warning can be suppressed by adding a comment like /* fall through */ at the appropriate places to indicate that the fallthrough is intended. --=20 Cheers, Stephen Rothwell --Sig_/98MDSry6jDRHt9Ep1W=uTQv Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAlv/MbwACgkQAVBC80lX 0Gxf2Qf/YWrIZvqMmkjx8UMwGPfDXUI/bw5l7GEJy03urzZJWem+77ggWgl70r0E AL6O4xHPzcv/TAEz+zqb3mae18N/k9uZudqIBQggxi/oPmQTZSQj7mIw0y3mEhRZ pOG0v1r3d4P5S7rvi6WTrwNnbzKYWFxIUFyIRCMNyrSB7Sk7DnjCjGwtyXctG2V8 ZqsJKh6EaCpKVUEfCbxry8VOLN/JRjAOydkGWwAifvNsFcTqG8N+uinoZSd2mn/C N+lPshmqYmUJvCETKcABdLEcBY6IVQdoCRYgXO894VGxdlROBWPYGcVsnKteauRG 3BuPWJbwz9C+IzUobaDc5S9LPA5BpQ== =+fzU -----END PGP SIGNATURE----- --Sig_/98MDSry6jDRHt9Ep1W=uTQv--
