Could you apply these patches and send them to Tom? These are important
fixes to make USB work properly on the dragonboard410c board and they
have been on the list for a few months now. There is already an ack from
Casey as well.

Or would it be easier for you if Casey applies them? I'm sure that would
work too. :)

Thanks,
Stephan
