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" * tag 'usb-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits) usb: gadget: fsl_qe_udc: Add missing semicolon in qe_ep_dequeue() dt-bindings: usb: mtk-xhci: add compatible for mt8186 usb: dwc3: Issue core soft reset before enabling run/stop usb: gadget: Makefile: remove ccflags-y USB: usb-storage: Fix use of bitfields for hardware data in ene_ub6250.c usb: gadget: eliminate anonymous module_init & module_exit usb: usbip: eliminate anonymous module_init & module_exit xen/usb: harden xen_hcd against malicious backends usb: dwc3: gadget: Wait for ep0 xfers to complete during dequeue usb: dwc3: gadget: move cmd_endtransfer to extra function usb: dwc3: gadget: ep_queue simplify isoc start condition xen/usb: don't use arbitrary_virt_to_machine() usb: isp1760: remove redundant max_packet() macro usb: oxu210hp-hcd: remove redundant call to max_packet() macro usb: common: usb-conn-gpio: Make VBUS supply completely optional USB: storage: ums-realtek: fix error code in rts51x_read_mem() usb: early: xhci-dbc: Fix xdbc number parsing usb: early: xhci-dbc: Remove duplicate keep parsing x86/tsc: Be consistent about use_tsc_delay() usb: gadget: udc: s3c2410: remove usage of list iterator past the loop body ...
