Merge tag 'usb-6.10-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 6.10-rc1. Nothing hugely earth-shattering, just constant forward progress for hardware support of new devices and cleanups over the drivers. Included in here are: - Thunderbolt / USB 4 driver updates - typec driver updates - dwc3 driver updates - gadget driver updates - uss720 driver id additions and fixes (people use USB->arallel port devices still!) - onboard-hub driver rename and additions for new hardware - xhci driver updates - other small USB driver updates and additions for quirks and api changes All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (154 commits) drm/bridge: aux-hpd-bridge: correct devm_drm_dp_hpd_bridge_add() stub usb: fotg210: Add missing kernel doc description usb: dwc3: core: Fix unused variable warning in core driver usb: typec: tipd: rely on i2c_get_match_data() usb: typec: tipd: fix event checking for tps6598x usb: typec: tipd: fix event checking for tps25750 dt-bindings: usb: qcom,dwc3: fix interrupt max items usb: fotg210: Use *-y instead of *-objs in Makefile usb: phy: tegra: Replace of_gpio.h by proper one usb: typec: ucsi: displayport: Fix potential deadlock usb: typec: qcom-pmic-typec: split HPD bridge alloc and registration usb: musc: Remove unused list 'buffers' usb: dwc3: Wait unconditionally after issuing EndXfer command usb: gadget: u_audio: Clear uac pointer when freed. usb: gadget: u_audio: Fix race condition use of controls after free during gadget unbind. dt-bindings: usb: dwc3: Add QDU1000 compatible usb: core: Remove the useless struct usb_devmap which is just a bitmap MAINTAINERS: Remove {ehci,uhci}-platform.c from ARM/VT8500 entry USB: usb_parse_endpoint: ignore reserved bits usb: xhci: compact 'trb_in_td()' arguments ...
