Merge tag 'usb-5.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB driver fixes from Greg KH:
"Here are some small USB driver fixes and new device ids for 5.19-rc3
They include:
- new usb-serial driver device ids
- usb gadget driver fixes for reported problems
- cdnsp driver fix
- dwc3 driver fixes for reported problems
- dwc3 driver fix for merge problem that I caused in 5.18
- xhci driver fixes
- dwc2 memory leak fix
All of these have been in linux-next for a while with no reported
issues"
