Subject: [PATCH] Fix SH4 DMAC API
To: Paul Mundt <le...@li...>
Cc: lin...@vg..., lin...@so...
This patch fixes the DMA cascade by masking the correct bits.
Tested and working with Dreamcast PVR2 DMA. With this patch applied
the existing mainline code in arch/sh/drivers/dma/dma-sh.c works,
whereas before I was patching that to get round this problem.
