| Subject: crypto: ixp4xx - Remove bogus BUG_ON on scattered dst buffer |
| |
| commit f898c522f0e9ac9f3177d0762b76e2ab2d2cf9c0 upstream. |
| |
| This patch removes a bogus BUG_ON in the ablkcipher path that |
| triggers when the destination buffer is different from the source |
| buffer and is scattered. |
