MAINTAINERS: merge SWIOTLB SUBSYSTEM into DMA MAPPING HELPERS

bulwahn · Christoph Hellwig · commit 91fd38ea7589 · 2022-09-22T17:28:21.000+02:00
Commit 78013ea ("x86: remove the IOMMU table infrastructure") refactored the generic swiotlb/swiotlb-xen setup into pci-dma.c, but misses to adjust MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about broken references. As only include/linux/swiotlb.h is unique to the SWIOTLB SUBSYSTEM section and Christoph is maintainer of DMA MAPPING HELPERS and SWIOTLB SUBSYSTEM, just merge those two sections. Leave the small architecture-dependent pieces to the arch maintainers. Further, update the XEN SWIOTLB SUBSYSTEM to include all swiotlb-xen headers and replace the pattern in drivers with the specific one file that matches this pattern.
