X-Git-Tag: omap-for-v3.16/fixes-against-rc1~177^2~1^2~5 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=10df350977b15d44dba0b3b44e3da7989711cb8d;p=pandora-kernel.git ASoC: Intel: Fix Audio DSP usage when IOMMU is enabled. The Intel IOMMU requires that the ACPI device is used to allocate all DMA memory buffers. This means we need to pass the DMA device pointer into child component devices that allocate DMA memory. We also only set the DMA mask for the ACPI device now instead of for each component device. Signed-off-by: Liam Girdwood Signed-off-by: Mark Brown --- Reading git-diff-tree failed
