register_platform_device_full() can setup the DMA mask provided the appropriate member is set in struct platform_device_info. So lets make that be the case. This avoids a direct reference to the DMA masks by this driver. Signed-off-by: Russell King <redacted> --- drivers/dma/edma.c | 6 ++---- 1 files changed, 2 insertions(+), 4 deletions(-)
