Browse Source 
Use uintptr_t for for pointer arithmmatic instead of char *
to fix following CERT-C violations.
cert_exp36_c_violation: Pointer "char *" is more strictly aligned
 than pointer "struct gk20a_event_id_data_rmos const *".

cert_exp36_c_violation: Pointer "struct nvgpu_clk_dev_rmos *" is
 more strictly aligned than pointer "char *".
