            Bug ID: 87576
           Summary: Null dereference in npramin_finit
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: rjgleits-Bdlq13kUjeyLZ21kGMrzwg@public.gmane.org

fix null dereference oops in nouveau.ko

This problem manifests when chipset is < nv50. In this case, pramin_init
returns NULL. mthd->data is then set to this value in shadow_method. Later,
mthd-> data is passed as a parameter to pramin_fini. The result is a kernel
oops. The attached patch takes care of that.

Best Wishes,

Bob Gleitsmann
