| Subject: tty: moxa: fix bit test in moxa_start() |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| commit 58112dfbfe02d803566a2c6c8bd97b5fa3c62cdc upstream. |
| |
| This is supposed to be doing a shift before the comparison instead of |
| just doing a bitwise AND directly. The current code means the start() |
| just returns without doing anything. |
