[PATCH 2/3] usb: dwc2: host: Giveback URB in tasklet context

In commit 94dfd7edfd5c ("USB: HCD: support giveback of URB in tasklet context") support was added to give back the URB in tasklet context. Let's take advantage of this in dwc2. This speeds up the dwc2 interrupt handler considerably. Signed-off-by: Douglas Anderson --- drivers/usb/dwc2/hcd.c |
