USB fixes for 5.18-rc7
Here are some small fixes for reported issues with some USB drivers. They include: - xhci fixes for xhci-mtk platform driver - typec driver fixes for reported problems. - cdc-wdm read-stuck fix - gadget driver fix for reported race condition - new usb-serial driver ids All of these have been in linux-next with no reported problems.
