So only <mach/dma.h> should be included in driver not <plat/dma.h> for Samsung DMA now. However I know, Boojin Kim (Cc'ed) will clean up the headers for DMA. So if you agree, please pick this up into your tree with my ack. Acked-by: Kukjin Kim <kgene.kim@xxxxxxxxxxx> Note, if this is ok to you, I will post above fix (drivers/crypto/s5p-sss.c) to crypto mailing list too. Thanks.
