[v4,0/6] USB: UDC: Fix memory leaks by expanding the API

Message

Peter Chen Aug. 21, 2020, 2:55 a.m. UTC

This series expands the UDC API to fix some long-standing memory leaks
in the net2280 and net2272 drivers. And with expanding APIs, it could
manage cdns3 and dwc3 gadget device memory better without the hacks
at UDC core.

Changes for v4:
- Add Greg and Alan's reviewed-by.

Changes for v3:
- Rebase the latest usb/next, and fix one build error for dwc3 [Patch 5/6]
