CVE-2023-53284: drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init()
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: check for null return of devmkzalloc() in dpuwritebackinit()
Because of the possilble failure of devmkzalloc(), dpuwbconn might be NULL and will cause null pointer dereference later.
Therefore, it might be better to check it and directly return -ENOMEM.
