commit: e39d40c65dfd8390b50c03482ae9e289b8a8f351 From: Gusakov Andrey <[email protected]> Date: Sat, 3 Mar 2012 07:32:36 +0900 Subject: ARM: S3C24XX: DMA resume regression fix
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.
