[igt-dev] [PATCH i-g-t 2/4] tools/intel_watermark: Don't do intel_register_access_fini() too early on hsw/bdw

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The tool will segfault if we try to the WM_DBG read/write after
intel_register_access_fini(). So move intel_register_access_fini()
to the very end.
