usb: host: xhci: update event ring dequeue pointer on purpose
On some situations, the software handles TRB events slower
than adding TRBs, then xhci_handle_event can't return zero
long time, the xHC will consider the event ring is full,
and trigger "Event Ring Full" error, but in fact, the software
has already finished lots of events, just no chance to
update ERDP (event ring dequeue pointer).
In this commit, we force update ERDP if half of TRBS_PER_SEGMENT
events have handled to avoid "Event Ring Full" error.

usbip: Fix uninitialized symbol 'nents' in stub_recv_cmd_submit()
Smatch reported that nents is not initialized and used in
stub_recv_cmd_submit(). nents is currently initialized by sgl_alloc()
and used to allocate multiple URBs when host controller doesn't
support scatter-gather DMA. The use of uninitialized nents means that
buf_len is zero and use_sg is true. But buffer length should not be
zero when an URB uses scatter-gather DMA.
To prevent this situation, add the conditional that checks buf_len
and use_sg. And move the use of nents right after the sgl_alloc() to
avoid the use of uninitialized nents.
If the error occurs, it adds SDEV_EVENT_ERROR_MALLOC and stub_priv
will be released by stub event handler and connection will be shut
down.

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.

usb: typec: ucsi: Simplified registration and I/O API
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.

USB: serial: ch341: reimplement line-speed handling
The current ch341 divisor algorithm was known to give inaccurate results
for certain higher line speeds. Jonathan Olds <jontio@i4free.co.nz>
investigated this, determined the basic equations used to derive the
divisors and confirmed them experimentally [1].
The equations Jonathan used could be generalised further to:
baudrate =
48000000 / (2^(12 - 3 * ps - fact) * div), where
0 <= ps <= 3,
0 <= fact <= 1,
2 <= div <= 256 if fact = 0, or
9 <= div <= 256 if fact = 1
which will also give better results for lower rates.
Notably the error is reduced for the following standard rates:
1152000 (4.0% instead of 15% error)
921600 (0.16% instead of -7.5% error)
576000 (-0.80% instead of -5.6% error)
200 (0.16% instead of -0.69% error)
134 (-0.05% instead of -0.63% error)
110 (0.03% instead of -0.44% error)
but also for many non-standard ones.
The current algorithm also suffered from rounding issues (e.g.
requesting 2950000 Bd resulted in a rate of 2 MBd instead of 3 MBd and
thus a -32% instead of 1.7% error).
The new algorithm was inspired by the current vendor driver even if that
one only handles two higher rates that require fact=1 by hard coding the
corresponding divisors [2].
Michael Dreher <michael@5dot1.de> also did a similar generalisation of
Jonathan's work and has published his results with a very good summary
that provides further insights into how this device works [3].

Pull powerpc fixes from Michael Ellerman:
"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"
