Felipe, Greg,
It is clearly a regression and material for 4.8-fixes. But I do know
that we are very late in the process :-(
Please do what you can to make it progress before 4.8-final but I'm
truly aware of the challenge.
Thanks to Richard for finding this and Alexandre for the quick correction.
Bye,

Any chance that we can have it (aka ping)?

Sorry, I had missed this one. Greg, seems like this would be the only
pending fix. Do you want it in a pull request or would you prefer to
just pick it up as a patch? Works either way for me. In case you decide
to pick it up as a patch:
Acked-by: Felipe Balbi <felipe.balbi@linux.intel.com>
If you prefer to pick it up as a pull request, I already have the patch
in my 'fixes' branch, just need to tag it and send it to you.

Felipe,
We agreed to delay this patch after the merge window is closed. But I
feel that it's beginning to be urgent to make this patch go forward:
actual users of our kernel are facing the issue:
https://lkml.org/lkml/2016/10/17/493
We're already at -rc2 and I don't see USB-fixes included...
Best regards,
