+Subject: qla2xxx: fix kernel NULL pointer access
+Origin: https://git.kernel.org/linus/78c2106a50e067f7168ee8c0944baaeb0e988272
+
+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().
