Hi Greg,
Today's linux-next merge of the usb tree got a conflict in
drivers/usb/dwc3/gadget.c between commit f4a53c55117b ("usb: dwc3:
gadget: fix pending isoc handling") from the usb.current tree and commit
348e026fafe2 ("usb: dwc3: gadget: Fix sparse warnings") from the usb tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
