Subject: [PATCH v3] ARM: S3C24XX DMA resume regression fix
Date: Thu, 1 Mar 2012 17:53:51 +0400 [thread overview]
Message-ID: <1330610031-2237-1-git-send-email-dron0gus@gmail.com> (raw)
In-Reply-To: <077201ccf767c6d1ec05475c40$%kim@samsung.com>
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.
