## Overview

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read()

If kzalloc() fails in lpfc_sli4_cgn_params_read(), then we rely on
lpfc_read_object()'s routine to NULL check pdata.

Currently, an early return error is thrown from lpfc_read_object() to
protect us from NULL ptr dereference, but the errno code is -ENODEV.

Change the errno code to a more appropriate -ENOMEM.

## Affected

- `Linux >= 72df8a452883b0be334396acba07df77c3c3f6c7 < 67b8343998b84418bc5b5206aa01fe9b461a80ef`

- `Linux >= 72df8a452883b0be334396acba07df77c3c3f6c7 < 908dd9a0853a88155a5a36018c7e2b32ccf20379`
- `Linux >= 72df8a452883b0be334396acba07df77c3c3f6c7 < 312320b0e0ec21249a17645683fe5304d796aec1`
