#     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 іmplementation (me)
#     
#     * tag 'dma-mapping-5.15' of git://git.infradead.org/users/hch/dma-mapping: (31 commits)
