I still have the same problems as with the previous revision: 


This is still not runtime-suspending when I use my DMA test in linking
mode.

If I put a large enough period between transfers, it should autosuspend
during transfers.  It seems to do auto-suspend and resume once, but then
it never suspends again.

I tested with my dmatest module[1], and loaded with:

  # insmod ./dmatest.ko linking=1 forever=1 forever_period=1024

Not only does it not auto-suspend between transfers (which I expected),
it also doesn't suspend after removing the module which stops all active
channels.
