Merge tag 'usb-6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are some small USB fixes and new device ids for 6.19-rc6 Included in here are: - new usb-serial device ids - dwc3-apple driver fixes to get things working properly on that hardware platform - ohci/uhci platfrom driver module soft-deps with ehci to remove a runtime warning that sometimes shows up on some platforms. - quirk for broken devices that can not handle reading the BOS descriptor from them without going crazy. - usb-serial driver fixes - xhci driver fixes - usb gadget driver fixes All of these except for the last xhci fix has been in linux-next for a while. The xhci fix has been reported by others to solve the issue for them, so should be ok" * tag 'usb-6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: xhci: sideband: don't dereference freed ring when removing sideband endpoint usb: gadget: uvc: retry vb2_reqbufs() with vb_vmalloc_memops if use_sg fail usb: gadget: uvc: return error from uvcg_queue_init() usb: gadget: uvc: fix interval_duration calculation usb: gadget: uvc: fix req_payload_size calculation usb: dwc3: apple: Ignore USB role switches to the active role usb: host: xhci-tegra: Use platform_get_irq_optional() for wake IRQs USB: OHCI/UHCI: Add soft dependencies on ehci_platform usb: dwc3: apple: Set USB2 PHY mode before dwc3 init USB: serial: f81232: fix incomplete serial port generation USB: serial: ftdi_sio: add support for PICAXE AXE027 cable USB: serial: option: add Telit LE910 MBIM composition usb: core: add USB_QUIRK_NO_BOS for devices that hang on BOS descriptor dt-bindings: usb: qcom,dwc3: Correct MSM8994 interrupts dt-bindings: usb: qcom,dwc3: Correct IPQ5018 interrupts tcpm: allow looking for role_sw device in the main node usb: dwc3: Check for USB4 IP_NAME
