dma-mapping: fix handling of dma-ranges for reserved memory (again)
[ Upstream commit
a445e940ea686fc60475564009821010eb213be3 ]
Daniele reported that issue previously fixed in
c41f9ea998f3
("drivers: dma-coherent: Account dma_pfn_offset when used with device
tree") reappear shortly after
43fc509c3efb ("dma-coherent: introduce
interface for default DMA pool") where fix was accidentally dropped.
Lets put fix back in place and respect dma-ranges for reserved memory.
Fixes:
43fc509c3efb ("dma-coherent: introduce interface for default DMA pool")
