Merge tag 'usb-5.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are some small USB fixes for 5.6-rc7. And there's a thunderbolt driver fix thrown in for good measure as well. These fixes are: - new device ids for usb-serial drivers - thunderbolt error code fix - xhci driver fixes - typec fixes - cdc-acm driver fixes - chipidea driver fix - more USB quirks added for devices that need them. All of these have been in linux-next with no reported issues" * tag 'usb-5.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: USB: cdc-acm: fix rounding error in TIOCSSERIAL USB: cdc-acm: fix close_delay and closing_wait units in TIOCSSERIAL usb: quirks: add NO_LPM quirk for RTL8153 based ethernet adapters usb: chipidea: udc: fix sleeping function called from invalid context USB: serial: pl2303: add device-id for HP LD381 USB: serial: option: add ME910G1 ECM composition 0x110b usb: host: xhci-plat: add a shutdown usb: typec: ucsi: displayport: Fix a potential race during registration usb: typec: ucsi: displayport: Fix NULL pointer dereference USB: Disable LPM on WD19's Realtek Hub usb: xhci: apply XHCI_SUSPEND_DELAY to AMD XHCI controller 1022:145c xhci: Do not open code __print_symbolic() in xhci trace events thunderbolt: Fix error code in tb_port_is_width_supported()
