| Subject: b43: refuse to load unsupported firmware |
| To: greg@kroah.com |
| Cc: linux-wireless@vger.kernel.org, b43-dev@lists.infradead.org, roman-vl@meta.ua, Rafał Miłecki <zajec5@gmail.com> |

| |
| [This patch is supposed to be applied in 3.1 (and maybe older) branches only.] |
| |
| New kernels support newer firmware that users may try to incorrectly use |
| with older kernels. Display error and explain the problem in such a case |
