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.
