In s3c24xx_dma_get_phy(), variable ‘cdata’ is initialized but never used, which
leads to warning with W=1. Removing this make pdata unused.
drivers/dma/s3c24xx-dma.c: In function ‘s3c24xx_dma_get_phy’:
drivers/dma/s3c24xx-dma.c:293:30: warning: variable ‘cdata’ set but not used [-Wunused-but-set-variable]
struct s3c24xx_dma_channel *cdata;
So remove both of them.
