Subject: ARM: 8419/1: dma-mapping: harmonize definition of DMA_ERROR_CODE
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=96231b2686b53f71838a335bdc404cb5285d1a01;p=linux-beck.git

ARM: 8419/1: dma-mapping: harmonize definition of DMA_ERROR_CODE

All architectures except arm that define DMA_ERROR_CODE are casting it
to (dma_addr_t) - as it is always compared to dma_addr_t in arm as well
this could be harmonized.
