Merge tag 'usb-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are some small fixes for 5.3-rc2. All of these resolve some
  reported issues, some more than others :)

  Included in here is:

   - xhci fix for an annoying issue with odd devices

   - reversion of some usb251xb patches that should not have been merged

   - usb pci quirk additions and fixups

   - usb storage fix

   - usb host controller error test fix

  All of these have been in linux-next with no reported issues"

* tag 'usb-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  xhci: Fix crash if scatter gather is used with Immediate Data Transfer (IDT).
  usb: usb251xb: Reallow swap-dx-lanes to apply to the upstream port
  Revert "usb: usb251xb: Add US port lanes inversion property"
  Revert "usb: usb251xb: Add US lanes inversion dts-bindings"
  usb: wusbcore: fix unbalanced get/put cluster_id
  usb/hcd: Fix a NULL vs IS_ERR() bug in usb_hcd_setup_local_mem()
  usb-storage: Add a limitation for blk_queue_max_hw_sectors()
  usb: pci-quirks: Minor cleanup for AMD PLL quirk
  usb: pci-quirks: Correct AMD PLL quirk detection

- power-on-time-ms : Specifies the time it takes from the time the host
initiates the power-on sequence to a port until the port has adequate
power. The value is given in ms in a 0 - 510 range (default is 100ms).
- swap-dx-lanes : Specifies the downstream ports which will swap the
differential-pair (D+/D-), default is not-swapped.
- swap-us-lanes : Selects the upstream port differential-pair (D+/D-)
swapping (boolean, default is not-swapped)
