| Subject: qla2xxx: fix kernel NULL pointer access |
| |
| From: Himanshu Madhani <himanshu.madhani@qlogic.com> |
| |
| commit 78c2106a50e067f7168ee8c0944baaeb0e988272 upstream. |
| |
| This patch is to fix regression added by commit id |
| 51a07f84649d2be206c4c2ad9a612956db0c2f8c. |
| |
| When allocating memory for new session original patch does |
| not assign vha to op->vha resulting into NULL pointer |
| access during qlt_create_sess_from_atio(). |
