Merge tag 'dma-mapping-5.15' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig:
- fix debugfs initialization order (Anthony Iliopoulos)
- use memory_intersects() directly (Kefeng Wang)
- allow to return specific errors from ->map_sg (Logan Gunthorpe,
Martin Oliveira)
- turn the dma_map_sg return value into an unsigned int (me)
- provide a common global coherent pool Ń–mplementation (me)
