ARM: S3C24XX: don't use uninitialized variable in dma.c
Commit 8970ef47 (S3C24XX: Remove hardware specific registers from DMA calls) removed the parameter dcon in s3c2410_dma_config() and calculates it on its own. So the debug-output for the old parameter can go, too. Fixes: arch/arm/plat-s3c24xx/dma.c: In function 's3c2410_dma_config': arch/arm/plat-s3c24xx/dma.c:1030:2: warning: 'dcon' is used uninitialized in this function Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
