From f67637ee4b5d90d41160d755b9a8cca18c394586 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 6 Dec 2006 20:38:54 -0800 Subject: [PATCH] Add struct dev pointer to dma_is_consistent() dma_is_consistent() 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_is_consistent to take a struct device pointer as first argument and fix the sole caller to pass it. Signed-off-by: Ralf Baechle Cc: James Bottomley Cc: "David S.
