Input updates for v6.8-rc7

- a revert of endpoint checks in bcm5974 - the driver is being naughty
  and pokes at unclaimed USB interface, so the check fails. We need to
  fix the driver to claim both interfaces, and then re-implement the
  endpoints check

- a fix to Synaptics RMI driver to avoid UAF on driver unload or device
  unbinding

- a few new VID/PIDs added to xpad game controller driver

- a change to gpio_keys_polled driver to quiet it when GPIO causes probe
  deferral.
