From: Laura Abbott <lauraa@xxxxxxxxxxxxxx>
Subject: common: dma-mapping: Swap function order
Fix the order of dma_common_contiguous_remap and
dma_common_pages_remap to avoid function declaration errors:
drivers/base/dma-mapping.c: In function 'dma_common_contiguous_remap':
drivers/base/dma-mapping.c:294: error: implicit declaration of
function 'dma_common_pages_remap'
drivers/base/dma-mapping.c:294: warning: assignment makes pointer from
integer without a cast
drivers/base/dma-mapping.c: At top level:
drivers/base/dma-mapping.c:308: error: conflicting types for
'dma_common_pages_remap'
drivers/base/dma-mapping.c:294: error: previous implicit declaration
of 'dma_common_pages_remap' was here
