[PATCH v4 05/11] cxl: Clean up adapter MMIO unmap path.

2015-08-12 Thread Daniel Axtens

- MMIO pointer unmapping is guarded by a null pointer check. However, iounmap doesn't null the pointer, just invalidate it. Therefore, explicitly null the pointer after unmapping. - afu_desc_mmio also needs to be unmapped. - PCI regions are allocated in cxl_map_adapter_regs.
