Arnd Bergmann 6f4722b1d1 dmaengine: dw-edma: fix endianess confusion ... When building with 'make C=1', sparse reports an endianess bug: drivers/dma/dw-edma/dw-edma-v0-debugfs.c:60:30: warning: cast removes address space of expression drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: warning: incorrect type in argument 1 (different address spaces) drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: expected void const volatile [noderef] <asn:2>*addr drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: got void *[assigned] ptr drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: warning: incorrect type in argument 1 (different address spaces) drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: expected void const volatile [noderef] <asn:2>*addr drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: got void *[assigned] ptr drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: warning: incorrect type in argument 1 (different address spaces) drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: expected void const volatile [noderef] <asn:2>*addr drivers/dma/dw-edma/dw-edma-v0-debugfs.c:86:24: got void *[assigned] ptr The current code is clearly wrong, as it passes an endian-swapped word into a register function where it gets swapped again. Just pass the variables directly into lower_32_bits()/upper_32_bits().
