From: Thomas Hellstrom <redacted> 3.4.108-rc1 review patch. If anyone has any objections, please let me know. ------------------ commit 3458390b9f0ba784481d23134798faee27b5f16f upstream. To take down the MOB and GMR memory types, the driver may have to issue fence objects and thus make sure that the fence manager is taken down after those memory types. Reorder device init accordingly.
