From d3fa72e4556ec1f04e46a0d561d9e785ecaa173d Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 6 Dec 2006 20:38:56 -0800 Subject: [PATCH] Pass struct dev pointer to dma_cache_sync() Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync to take a struct device pointer as first argument and fix all its callers to pass it. Signed-off-by: Ralf Baechle Cc: James Bottomley Cc: "David S.
