Your next branch doesn't have these prerequisite patches from mainline:
d3abda5a98a1 ("usb: dwc3: gadget: Clear started flag for non-IOC")
2d7b78f59e02 ("usb: dwc3: ep0: Clear started flag on completion")

Will you rebase on v5.5 rc-x? Let me know how we can proceed to resolve 
the conflict.

Also, have you a chance to take a look at these patches:
https://patchwork.kernel.org/project/linux-usb/list/?series=214669
* usb: dwc3: gadget: Properly set maxpacket limit
* usb: dwc3: Fix GTXFIFOSIZ.TXFDEP macro name


Thanks!
Thinh
