| Subject: [PATCH 09/39] CHROMIUM: i965: Return NULL if we don't have a miptree |
| |
| If we have no miptree (irb->mt == NULL) we still go ahead and look at |
| the stencil miptree, which causes crashes. Instead, let's return NULL if |
| we don't have a miptree, which will be correctly handled later. |

| TEST=can't reproduce the bug, but compiles and runs |
