Merge tag 'usb-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel…
…/git/gregkh/usb
Pull USB/Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
Nothing major in here, just lots of little improvements and cleanups
and new device support. Highlights are:
- list iterator fixups for when we walk past the end of the list (a
common problem that was cut/pasted in almost all USB gadget
drivers)
- xen USB driver "hardening" for malicious hosts
- xhci driver updates and fixes for more hardware types
- xhci debug cable fixes to make it actually work again
- usb gadget audio driver improvements
- usb gadget storage fixes to work with OS-X
- lots of other small usb gadget fixes and updates
- USB DWC3 driver improvements for more hardware types
- Lots of other small USB driver improvements
- DTS updates for some USB platforms
All of these have been in linux-next for a while with no reported
issues"

| Date: February 2022 | ||
| Contact: Souradeep Chowdhury <quic_schowdhu@quicinc.com> | ||
| Description: | ||
| The Enable/Disable sysfs interface for Embedded | ||
| USB Debugger(EUD). This enables and disables the | ||
| EUD based on a 1 or a 0 value. By enabling EUD, | ||
| the user is able to activate the mini-usb hub of | ||
| EUD for debug and trace capabilities. |
