I assume there is a v4 coming due to rmk's comments on patch 5.
I couldn't figure out where to null the of_node in error paths, but in testing
we did put a line of code to null the of_node on release.

but...
As an aside,
I was hoping this series would magically fix a problem
with the imx6q-evi which has forced us to disable
runtime power management. But it did not. :(

I also see a similar problem on a mx28 board with a hub.

Does it help in your case if you pass 'usbcore.autosuspend=-1' in the
kernel command line?

Thanks a million, Fabio!

'usbcore.autosuspend=-1' quiets the errors.

P.S. I guess this technically is a bug in chipidea usb.
I'll give it a quick once over, though I am not very familiar
with USB core or the CI driver.
