Really? Didn't silence it for me when I tested this patch.

Also, please see

https://lore.kernel.org/linux-usb/DBBPR04MB7979502194410BB1AE96DF038BCC0@DBBPR04MB7979.eurprd04.prod.outlook.com/T/#m7f73fdd57c0f1577fb610dcaf28646b53fa7dc26

(what a strange URL)

I now get these 2 warnings:

In file included from ../drivers/usb/cdns3/core.c:23:0:
../drivers/usb/cdns3/host-export.h:27:44: warning: ‘struct usb_hcd’ declared inside parameter list will not be visible outside of this definition or declaration
static int xhci_cdns3_suspend_quirk(struct usb_hcd *hcd)
^~~~~~~
CC [M] drivers/usb/gadget/function/uvc_queue.o
