Thanks,
Patches look good but something must have changed since you submitted them.
I can't apply them neatly on usb-next, usb-linus, 5.17, or 5.17-rc8


On top of usb-next I get:
Applying: usb: host: xhci-plat: create shared hcd after having added main hcd
error: patch failed: drivers/usb/host/xhci-plat.c:313
error: drivers/usb/host/xhci-plat.c: patch does not apply
