Subject: RE: [PATCH v3] USB: dummy-hcd: fix power budget for SuperSpeed mode

No, this fix is not for specific commit since the POWER_BUDGET(500mA) is used for 
SuperSpeed mode when dummy hcd added SuperSpeed support in commit(1cd8fd2887).

And I think it should be imported to stable kernel(s) considering the "insufficient
available bus power error" mentioned in commit message really happens. We reproduced
this issue with linux-3.10, linux-4.9 which we use and confirmed it can be solved by
this modification.

Regards
Jacky
