dmaengine: at_hdmac: add a few const qualifiers
This prepares of_device_id.data becoming const. Without this change the following warning would occur: drivers/dma/at_hdmac.c: In function 'at_dma_get_driver_data': drivers/dma/at_hdmac.c:1228: warning: return discards qualifiers from pointer target type Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Dan Williams <dan.j.williams@intel.com> Cc: Vinod Koul <vinod.koul@intel.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
