Signed-off-by: Ryo Kataoka <[email protected]> Signed-off-by: Yoshihiro Kaneko <[email protected]> --- Hi Geert-san, I have also found patches to address this problem in DTS files which seems to be a good way to handle this problem.

This patch is based on the for-next branch of Mark Brown's spi tree. drivers/spi/spi-sh-msiof.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/spi/spi-sh-msiof.c b/drivers/spi/spi-sh-msiof.c index e57eec0..88ec049 100644 --- a/drivers/spi/spi-sh-msiof.c +++ b/drivers/spi/spi-sh-msiof.c @@ -1,6 +1,7 @@ /* * SuperH MSIOF SPI Master Interface * + * Copyright (C) 2014-2015 Renesas Electronics Corporation * Copyright (c) 2009 Magnus Damm * Copyright (C) 2014 Glider bvba * @@ -1072,10 +1073,7 @@ static int sh_msiof_request_dma(struct sh_msiof_spi_priv *p) return 0; } - /* The DMA engine uses the second register set, if present */ - res = platform_get_resource(pdev, IORESOURCE_MEM, 1); - if (!res) - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); master = p->master; master->dma_tx = sh_msiof_request_dma_chan(dev, DMA_MEM_TO_DEV, -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
