If anyone has any objections, please let me know. ------------------ From: Gusakov Andrey 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.
