Description
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Add a null ptr check for dpu_encoder_needs_modeset
The drm_atomic_get_new_connector_state() can return NULL if the
connector is not part of the atomic state. Add a check to prevent
a NULL pointer dereference.
This follows the same pattern used in dpu_encoder_update_topology()
within the same file, which checks for NULL before using conn_state.
