This patch replaces the static assignment of ~0 to dma_handle with DMA_ERROR_CODE to be consistent with other platforms.
Signed-off-by: Sean Paul <seanpaul@chromium.org> ---
Changes in v2: - Removed the check for DMA_ERROR_CODE in __dma_free_noncoherent the function shouldn't be called after failed allocation
