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().
