Merge branch 'cleanups/dma' into next/cleanup
Separate patches from Marek Szyprowski <m.szyprowski@samsung.com>: Commit e9da6e9905e639b0 ("ARM: dma-mapping: remove custom consistent dma region") replaced custom consistent memory handling, so setting consistent dma memory size is not longer required. This patch series cleans sub-architecture platform code to remove all calls to the obsolated init_consistent_dma_size() function and finally removes the init_consistent_dma_size() stub itself. * cleanups/dma: ARM: at91: remove obsoleted init_consistent_dma_size() ARM: u300: remove obsoleted init_consistent_dma_size() ARM: dma-mapping: remove init_consistent_dma_size() stub ARM: shmobile: remove obsoleted init_consistent_dma_size() ARM: davinci: remove obsoleted init_consistent_dma_size() ARM: samsung: remove obsoleted init_consistent_dma_size() Signed-off-by: Arnd Bergmann <arnd@arndb.de>
