USB: Remove remnants of Wireless USB and UWB
Wireless USB has long been defunct, and kernel support for it was removed in 2020 by commit caa6772db4c1 ("Staging: remove wusbcore and UWB from the kernel tree.").
Nevertheless, some vestiges of the old implementation still clutter up the USB subsystem and one or two other places. Let's get rid of them once and for all.
The only parts still left are the user-facing APIs in include/uapi/linux/usb/ch9.h. (There are also a couple of misleading instances, such as the Sierra Wireless USB modem, which is a USB modem made by Sierra Wireless.)

Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand.
It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact.
A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all.
This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
There were a couple of notable cases:
- csky still had the old "verify_area()" name as an alias.
- the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it)
- microblaze used the type argument for a debug printout
but other than those oddities this should be a total no-op patch.
I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though.

with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we should be all done.

USB: core: Remove redundant license text
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed.
No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb/core: consider link speed while looking at bMaxPower
The USB 2.0 specification says that bMaxPower is the maximum power consumption expressed in 2 mA units and the USB 3.0 specification says that it is expressed in 8 mA units. This patch adds a helper function usb_get_max_power() which computes the value based on config & usb_device's speed value. The the device descriptor dump computes the value on its own.

USB: hub_for_each_child should skip unconnected ports
This patch (as1619) improves the interface to the "hub_for_each_child" macro. The name clearly suggests that the macro iterates over child devices; it does not suggest that the loop will also iterate over unnconnected ports.
The patch changes the macro so that it will skip over unconnected ports and iterate only the actual child devices. The two existing call sites are updated to avoid testing for a NULL child pointer, which is now unnecessary.

USB: Fix race condition when removing host controllers
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file.
The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops.
The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

usb: move children to struct usb_port
The usb_device structure contains an array of usb_device "children". This array is only valid if the usb_device is a hub, so it makes no sense to store it there. Instead, store the usb_device child in its parent usb_port structure.
Since usb_port is an internal USB core structure, add a new function to get the USB device child, usb_hub_find_child(). Add a new macro, usb_hub_get_each_child(), to iterate over all the children attached to a particular USB hub.
Remove the printing the USB children array pointer from the usb-ip driver, since it's really not necessary.
