| Subject: rsi: fix potential null dereference in rsi_probe() |
| |
| From: Denis Efremov <efremov@linux.com> |
| |
| commit f170d44bc4ec2feae5f6206980e7ae7fbf0432a0 upstream. |
| |
| The id pointer can be NULL in rsi_probe(). It is checked everywhere except |
| for the else branch in the idProduct condition. The patch adds NULL check |
| before the id dereference in the rsi_dbg() call. |
| |
| Fixes: 54fdb318c111 ("rsi: add new device model for 9116") |
