Notes:

The order of authors with > 30 commits listed here is sorted by contributions
from high to low through ``git log --no-merges $@ | grep Author: | \
cut -d: -f2 | cut -d\< -f1 | sort | uniq -c | sort -n -r''. The list of minor
contributors is currently unsorted and contains people who have contributed
code ``in some way'' (e.g. on the upstream or maintenance repositories), either
through Git or email.

Note that we have taken over the maintenance and further development of Herbert
Haas' mausezahn [ˈmauzəˌtsa:n] utility after he passed away in 2011. There were
no Git commit statistics available from the import of his project. The project
is currently in a staging area, but will be fully integrated soon. (*)

implement what's on the TODO file and show an ongoing, active interest in
supporting netsniff-ng. What's in it for you? If you ever come to Switzerland,
you get a free beer on Daniel and you can meet some great people involved in
this project. ;)

<div class='commit-subject'>dmaengine: cppi41: Fix runtime PM timeouts with USB mass storage</div><div class='commit-msg'>Commit fdea2d09b997 ("dmaengine: cppi41: Add basic PM runtime support")
added runtime PM support for cppi41, but had corner case issues. Some of
the issues were fixed with commit 098de42ad670 ("dmaengine: cppi41: Fix
unpaired pm runtime when only a USB hub is connected"). That fix however
caused a new regression where we can get error -115 messages with USB on
BeagleBone when connecting a USB mass storage device to a hub.

This is because when connecting a USB mass storage device to a hub, the
initial DMA transfers can take over 200ms to complete and cppi41
autosuspend delay times out.

To fix the issue, we want to implement refcounting for chan_busy array
that contains the active dma transfers. Increasing the autosuspend delay
won't help as that the delay could be potentially seconds, and it's best
to let the USB subsystem to deal with the timeouts on errors.

The earlier attempt for runtime PM was buggy as the pm_runtime_get/put()
calls could get unpaired easily as they did not follow the state of
the chan_busy array as described in commit 098de42ad670 ("dmaengine:
cppi41: Fix unpaired pm runtime when only a USB hub is connected".

Let's fix the issue by adding pm_runtime_get() to where a new transfer
is added to the chan_busy array, and calls to pm_runtime_put() where
chan_busy array entry is cleared. This prevents any autosuspend timeouts
from happening while dma transfers are active.

only a USB hub is connected")
Fixes: fdea2d09b997 ("dmaengine: cppi41: Add basic PM runtime support")
