Re: [PATCH v3 0/5] usb: gadget: uvc: improve uvc gadget performance

I just realized that the previous series already should have been v3 and
this v4. However, the changelog of the patches is right and this is the
latest version. So there should be no need for resend.

Sorry for the mess, next time I will keep better bookkeeping.

This series improves the performance of the uvc video gadget by adding a
zero copy routine using the scatter list interface of the gadget. The
series also increases the amount of allocated requests depending of the
speed and it also reduces the interrupt load by only trigger on every
16th request in case of super-speed.
