CVE-2023-54122
drm/msm/dpu: Add check for cstate
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Add check for cstate
As kzalloc may fail and return NULL pointer,
it should be better to check cstate
in order to avoid the NULL pointer dereference
in __drm_atomic_helper_crtc_reset.
