This commit will fix the problem:
https://git.kernel.org/cgit/linux/kernel/git/balbi/usb.git/commit/?h=testing/next&id=6c97f002f678d5047bdf8a9e248dc50656c38ae2

I think we should consider it as a fix for this issue. Unfortunately
Felipe is on vacation at the moment. Greg, could help with this?

I will also be on vacation for the rest of the month and my access to
internet will be fairly limited.


Thanks,
