Pull tty / serial driver updates from Greg KH:
 "Here is the big set of tty and serial driver changes for 6.0-rc1.

  It was delayed from last week as I wanted to make sure the last commit
  here got some good testing in linux-next and elsewhere as it seemed to
  show up only late in testing for some reason.

  Nothing major here, just lots of cleanups from Jiri and Ilpo to make
  the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo).

  Also included in here is the obligatory n_gsm updates from Daniel
  Starke and lots of tiny driver updates and minor fixes and tweaks for
  other smaller serial drivers.

  All of these have been in linux-next for a while with no reported
  problems"

Pull tracing updates from Steven Rostedt:

 - Runtime verification infrastructure

   This is the biggest change here. It introduces the runtime
   verification that is necessary for running Linux on safety critical
   systems.

   It allows for deterministic automata models to be inserted into the
   kernel that will attach to tracepoints, where the information on
   these tracepoints will move the model from state to state.

   If a state is encountered that does not belong to the model, it will
   then activate a given reactor, that could just inform the user or
   even panic the kernel (for which safety critical systems will detect
   and can recover from).

 - Two monitor models are also added: Wakeup In Preemptive (WIP - not to
   be confused with "work in progress"), and Wakeup While Not Running
   (WWNR).

 - Added __vstring() helper to the TRACE_EVENT() macro to replace
   several vsnprintf() usages that were all doing it wrong.

 - eprobes now can have their event autogenerated when the event name is
   left off.

 - The rest is various cleanups and fixes.

The priv_dev assignment was moved below the if statement to avoid
potentially dereferencing ep before it was checked but priv_dev is used
in the dev_dbg() call.

To fix this, move the priv_dev and comp_desc assignments back to their
original spot and hoist the ep check above those assignments with a call
to pr_debug() instead of dev_dbg().

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of Thunderbolt and USB changes for 6.0-rc1.

  Lots of little things here, nothing major, just constant development

   - lots of typec changes and improvements for new hardware

   - new gadget controller driver

   - thunderbolt support for new hardware

   - the normal set of new usb-serial device ids and cleanups

   - loads of dwc3 controller fixes and improvements

   - mtu3 driver updates

   - testusb fixes for longtime issues (not many people use this tool it
     seems.)

   - minor driver fixes and improvements over the USB tree

   - chromeos platform driver changes were added and then reverted as
     they depened on some typec changes, but the cross-tree merges
     caused problems so they will come back later through the platform
     tree.

  All of these have been in linux-next for a while now with no reported

Merge ACPI device object management changes for v5.20-rc1.

 - Use the facilities provided by the driver core and some additional
   helpers to handle the children of a given ACPI device object in
   multiple places instead of using the children and node list heads in
   struct acpi_device which is error prone (Rafael Wysocki).

 - Fix ACPI-related device reference counting issue in the hisi_lpc bus
   driver (Yang Yingliang).

 - Drop the children and node list heads that are not needed any more
   from struct acpi_device (Rafael Wysocki).

 - Drop driver member from struct acpi_device (Uwe Kleine-König).

 - Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

  ACPI: bus: Drop unused list heads from struct acpi_device
  hisi_lpc: Use acpi_dev_for_each_child()

onboard_hub_power_on() already ensures the reset pulse width delay, so
