| Subject: media: dvb-usb: fix ununit-value in az6027_rc_query |
| |
| From: Pavel Skripkin <paskripkin@gmail.com> |
| |
| [ Upstream commit afae4ef7d5ad913cab1316137854a36bea6268a5 ] |
| |
| Syzbot reported ununit-value bug in az6027_rc_query(). The problem was |
| in missing state pointer initialization. Since this function does nothing |
| we can simply initialize state to REMOTE_NO_KEY_PRESSED. |
