Since commit d4ead16f50 ("USB: prevent char device open/deregister
race") core prevents further calls to open() after usb_deregister_dev()
returns so there's no need to use the interface data for
synchronisation.
This effectively reverts commit 54d2bc068f ("USB: fix locking in
idmouse") with respect to the open-disconnect race.
Note that the driver already uses a present flag to suppress I/O post
disconnect (even if all USB I/O take place at open).

As Mathias pointed out, the hub enters Cold Attach Status state and
requires a warm reset. However usb_reset_device() bails out early when
the device is in suspended state, as its callers port_event() and
hub_event() don't always resume the device.
Since there's nothing wrong to reset a suspended device, allow
usb_reset_device() to do so to solve the issue.

That data structure was used for constructing the commands
before executing them, but it was never really useful. Using
the structure just complicated the driver. The commands are
64-bit wide, so it is enough to simply fill a u64 variable.
No data structures needed.
This simplifies the driver considerable and makes it much
easier to for example add support for big endian systems
later on.

Adding more simplified API for interface registration and
read and write operations.
The registration is split into separate creation and
registration phases. That allows the drivers to properly
initialize the interface before registering it if necessary.
The read and write operations are supplied in a completely
separate struct ucsi_operations that is passed to the
ucsi_register() function during registration. The new read
and write operations will work more traditionally so that
the read callback function reads a requested amount of data
from an offset, and the write callback functions write the
given data to the offset. The drivers will have to support
both non-blocking writing and blocking writing. In blocking
writing the driver itself is responsible of waiting for the
completion event.
The new API makes it possible for the drivers to perform
tasks also independently of the core ucsi.c, and that should
allow for example quirks to be handled completely in the
drivers without the need to touch ucsi.c.
The old API is kept until all drivers have been converted to
the new API.

The USB sub-maintainers woke up this past week and sent a bunch of tiny
fixes. Here are a lot of small patches that that resolve a bunch of
reported issues in the USB core, drivers, serial drivers, gadget
drivers, and of course, xhci :)
All of these have been in linux-next with no reported issues.

Our recent cleanup of EEH led to an oops on bare metal machines when the cxl
(CAPI) driver creates virtual devices for an attached FPGA accelerator.
The "secure virtual machine" support we added in v5.4 had a bug if the kernel
was relocated (moved during boot), in those cases the signature of the kernel
text wouldn't verify and the Ultravisor would refuse to run the VM.
A recent change to disable interrupts before calling arch_cpu_idle_dead() caused
a WARN_ON() in our bare metal CPU offline code to always trigger.
The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the address
range crossed a segment (256MB) boundary which could lead to spurious faults.
Thanks to:
Christophe Leroy, Frederic Barrat, Michael Anderson, Nicholas Piggin, Sam
Bobroff, Thiago Jung Bauermann.
