From: Uwe Kleine-König <redacted> 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 <redacted> Cc: Nicolas Ferre <redacted> Cc: Dan Williams <redacted> Cc: Vinod Koul <redacted> --- drivers/dma/at_hdmac.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
