changing ring->sched.ready should be done only if the ring is

I don't think that this makes much difference. When the rings are
freed the hardware and software stack needs to be disabled quite some
time before.
Yes it doesn't make any difference. I wanted amdgpu_ring_fini() to
look bit cleaner.
Ok, you should note that in the subject and commit message. Something
like "cleanup amdgpu_ring_fini" / "Check the prerequisites before the
actual operation".
Otherwise if that is not clearly state somebody might think that this is
a bug fix and pick it up for backporting and we probably don't want that.
