Debarshi Dutta 2217e342d5 gpu: nvgpu: check for null pointer access ...

It is possible to have an invalid combination of the ioctl calls that
could result in a null pointer access in the function
gk20a_event_id_release(). The null pointer access can be prevented by
having a null check for a valid struct gk20a_event_id_data before
accessing its internal variables.
