Subject: [PATCH 23/95] ARM: S3C24XX: DMA resume regression fix
commit e39d40c65dfd8390b50c03482ae9e289b8a8f351 upstream.
s3c2410_dma_suspend suspends channels from 0 to dma_channels.
s3c2410_dma_resume resumes channels in reverse order. So
pointer should be decremented instead of being incremented.
