Hi, again

Current rcar-dmac is using DMAC error interrupt which will handle all
channel's error. But in this design, error handling itself will be
issue if user want to use virtualization, multi OS, etc.
This patch removes current DMAC error interrupt handling, and handle it
on each channel interrupt handler.

Just wondering, what's the usage pattern where this causes a problem?
Do you plan to export part of a SYS-DMAC instance to a guest?

"virtualization, multi OS" part is maybe misleading.
It will be problem on non virtualization, too.

How to maintain host/guest isolation?

This is another topic/issue, I think

I will post v3 patch, soon
