Merge tag 'usb-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB and Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt driver changes for
5.17-rc1.
Nothing major in here, just lots of little updates and cleanups. These
include:
- some USB header fixes picked from Ingo's header-splitup work
- more USB4/Thunderbolt hardware support added
- USB gadget driver updates and additions
- USB typec additions (includes some acpi changes, which were acked
by the ACPI maintainer)
- core USB fixes as found by syzbot that were too late for 5.16-final
- USB dwc3 driver updates
- USB dwc2 driver updates
- platform_get_irq() conversions of some USB drivers
- other minor USB driver updates and additions
All of these have been in linux-next for a while with no reported
issues"
