Pull USB and Thunderbolt fixes from Greg KH: "Here are some small Thunderbolt and USB driver fixes for 5.10-rc4 to solve some reported issues. Nothing huge in here, just small things: - thunderbolt memory leaks fixed and new device ids added - revert of problem patch for the musb driver - new quirks added for USB devices - typec power supply fixes to resolve much reported problems about charging notifications not working anymore All except the cdc-acm driver quirk addition have been in linux-next with no reported issues (the quirk patch was applied on Friday, and is self-contained)" * tag 'usb-5.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: usb: cdc-acm: Add DISABLE_ECHO for Renesas USB Download mode MAINTAINERS: add usb raw gadget entry usb: typec: ucsi: Report power supply changes xhci: hisilicon: fix refercence leak in xhci_histb_probe Revert "usb: musb: convert to devm_platform_ioremap_resource_byname" thunderbolt: Add support for Intel Tiger Lake-H thunderbolt: Only configure USB4 wake for lane 0 adapters thunderbolt: Add uaccess dependency to debugfs interface thunderbolt: Fix memory leak if ida_simple_get() fails in enumerate_services() thunderbolt: Add the missed ida_simple_remove() in ring_request_msix()
