Subject: [PATCH 9 of 9] ia64/x86/swiotlb: use enum dma_data_direciton in
dma_ops
From: Becky Bruce <beckyb@...nel.crashing.org>
SWIOTLB currently uses "int" as the type of the dma direction,
not "enum dma_data_direction as documented in DMA_API.txt. Now that
this code is about to become shared with powerpc, which uses
the enum, update the swiotlb code to use the enum as well. Doing this
requires changing all the arch's that use swiotlb use the enum also.
Signed-off-by: Becky Bruce <beckyb@...nel.crashing.org>
