CVE-2023-53284

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init() Because of the possilble failure of devm_kzalloc(), dpu_wb_conn might be NULL and will cause null pointer dereference later. Therefore, it might be better to check it and directly return -ENOMEM. Patchwork: https://patchwork.freedesktop.org/patch/512277/ [DB: fixed typo in commit message]
