When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic

Move the lock_class_key structure out of struct bus_type and into the
dynamic structure we create already for all bus_types registered with
the kernel.  This saves on static space and removes one more writable
field in struct bus_type.

In the future, the same field can be moved out of the struct class logic
because it shares this same private structure.

Most everyone will never notice this change, as lockdep is not enabled
in real systems so no memory or logic changes are happening for them.

__platform_driver_probe() pokes around in some bus and driver private
lists and locks in a way that is not needed at all.  The code only wants
to know if a device was bound to the driver that was registered, so walk
all devices on the bus to see if there was a match.  If there is not a
match, return an error.  This is the same logic as was originally
present, but just done in a simpler and more obvious way that is not a
layering violation.

In the reworking of the function __platform_driver_probe() over the

The driver core recently changed the uevent bus callback to take a const
pointer, and the maple_bus_uevent() was not correctly fixed up.  Instead
of fixing the function parameter types, just remove the callback
entirely as it does not do anything, so it is not necessary.

commit bd500361 ("ACPI: PPTT: Update acpi_find_last_cache_level()
to acpi_get_cache_info()")
updates the prototype of acpi_get_cache_info(). The cache 'levels'
is update through a pointer and not the return value of the function.

If CONFIG_ACPI_PPTT is not defined, acpi_get_cache_info() doesn't
update its *levels and *split_levels parameters and returns 0.
This can lead to a faulty behaviour.

Make acpi_get_cache_info() return an error code if CONFIG_ACPI_PPTT
is not defined.
Also,

In init_cache_level(), if no PPTT is present or CONFIG_ACPI_PPTT is
not defined, instead of aborting if acpi_get_cache_info() returns an
error code, just continue. This allows to try fetching the cache
information from clidr_el1.

of_device_uevent_modalias() does not modify the device pointer passed to
it, so mark it constant.  In order to properly do this, a number of
busses need to have a modalias function added as they were attempting to
just point to of_device_uevent_modalias instead of their bus-specific
modalias function.  This is fine except if the prototype for a bus and
device type modalias function diverges and then problems could happen.  To
prevent all of that, just wrap the call to of_device_uevent_modalias()
directly for each bus and device type individually.

Clear the class private pointer if __class_register() fails for it, so
as to allow its users to verify that the class is usable by checking
the value of that pointer.

For consistency, clear that pointer before freeing the object pointed
to by it in class_release().

We need the driver core fixes in here as well.

Pull another io_uring fix from Jens Axboe:
 "Just a single fix for a regression that happened in this release due
  to a poll change. Normally I would've just deferred it to next week,
  but since the original fix got picked up by stable, I think it's
  better to just send this one off separately.

  The issue is around the poll race fix, and how it mistakenly also got
  applied to multishot polling. Those don't need the race fix, and we
  should not be doing any reissues for that case. Exhaustive test cases
  were written and committed to the liburing regression suite for the
  reported issue, and additions for similar issues"

Pull char/misc driver fixes from Greg KH:
 "Here are some small char/misc and other subsystem driver fixes for
  6.2-rc5 to resolve a few reported issues. They include:

   - long time pending fastrpc fixes (should have gone into 6.1, my
     fault)

   - mei driver/bus fixes and new device ids

   - interconnect driver fixes for reported problems

   - vmci bugfix

   - w1 driver bugfixes for reported problems

  Almost all of these have been in linux-next with no reported problems,
  the rest have all passed 0-day bot testing in my tree and on the
  mailing lists where they have sat too long due to me taking a long
  time to catch up on my pending patch queue"
