P.S.: don't run means don't allow to run, by either feeding radeon.test=X or radeon.benchmark=1
Good catch. I applied a slightly different variant of the same idea.

Prevent NULL pointer dereference in case when radeon_ring_fini() did it's job.
Reading of r100_cp_ring_info and radeon_ring_gfx debugfs entries will lead to a KP if ring buffer was deallocated, e.g. on failed ring test. Seen on PA-RISC machine having "radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD)" issue.
