The Smatch checker flags svdm_version being uninitialized for Discover
Identity Messages within tcpm_pd_svdm for the CMDT_INIT case. Cable plugs
cannot initialize SVDM commands, however a port partner that isn't allowed
to communicate over SOP' could, which would result in the CMDT_INIT block
running for a received SOP' message.

First, initialize svdm_version for the TCPC_TX_SOP_PRIME case. If the
svdm_version returns as an error, we expect the received svdm to be the
result of Discover Identity that updates the value accordingly.

Next, drop all SOP' messages of type CMDT_INIT within tcpm_pd_svdm.

Finally, remove redundant call that assigns modep and pdev. Smatch will
raise an uninitialized symbol error over modep_prime and pdev_prime, but
both the assignment and use of these variables are guarded behind
a check for rx_sop_type == TCPC_TX_SOP_PRIME.

Ports with  _UPC (USB Port Capability) ACPI objects stating they are
"not connectable" are not wired to any connector or internal device.
They only exist inside the host controller.

These ports may not have an ACPI _PLD (Physical Location of Device)
object.

Rework the code so that _UPC is read even if _PLD does not exist, and
make sure the port->connect_type is set to "USB_PORT_NOT_USED" instead
of "USB_PORT_CONNECT_TYPE_UNKNOWN".

No bugs or known issues are reported due to possibly not parsing _UPC,
and thus leaving the port connect type as "unknown" instead of
"not used". Nice to have this fixed but no need to add it to stable
kernels, or urgency to get it upstream.

Minimal ACPI support was added to the Qualcomm DWC3 glue driver in order to
enable USB on SDM850 and SC8180X compute platforms. The support is still
functional, but unnoticed regressions in other drivers indicates that no
one actually booting any of platforms dependent on this implementation.

The functionality provides is the bare minimum and is not expected to aid
in the effort of bringing full ACPI support to the driver in the future.

Remove the ACPI code from the Qualcomm DWC3 glue driver to aid in the
implementation of improvements that are actually used like multiport and
flattening device tree.

Motivation
----------

The binary device object store (BOS) of a USB device consists of the BOS
descriptor followed by a set of device capability descriptors. One that is
of interest to users is the platform descriptor. This contains a 128-bit
UUID and arbitrary data, and it allows parties outside of USB-IF to add
additional metadata about a USB device in a standards-compliant manner.
Notable examples include the WebUSB and Microsoft OS 2.0 descriptors.

The kernel already retrieves and caches the BOS from USB devices if its
bcdUSB is >= 0x0201. Because the BOS is flexible and extensible, we export
the entire BOS to sysfs so users can retrieve whatever device capabilities
they desire, without requiring USB I/O or elevated permissions.

Implementation
--------------

Add bos_descriptors attribute to sysfs. This is a binary file and it works
the same way as the existing descriptors attribute. The file exists only if
the BOS is present in the USB device.

Also create a binary attribute group, so the driver core can handle the
creation of both the descriptors and bos_descriptors attributes in sysfs.

Two NEC uPD720200 adapters have been observed to randomly misbehave:
a Stop Endpoint command fails with Context Error, the Output Context
indicates Stopped state, and the endpoint keeps running. Very often,
Set TR Dequeue Pointer is seen to fail next with Context Error too,
in addition to problems from unexpectedly completed cancelled work.

The pathology is common on fast running isoc endpoints like uvcvideo,
but has also been reproduced on a full-speed bulk endpoint of pl2303.
It seems all EPs are affected, with risk proportional to their load.

Reproduction involves receiving any kind of stream and closing it to
make the device driver cancel URBs already queued in advance.

Deal with it by retrying the command like in the Running state.

A trb_in_td() call is used to determine if a completion event matches
any TRB of the currently executing TD. This function is told to start
searching right after the last finished TD, which is not at all where
the currently expected TD is guaranteed to begin, because some TDs in
between may have been cancelled.

Not only is a pointless work performed, but a bug resulting in the HC
executing cancelled TDs was seen to trick the driver into associating
events from a TD just cancelled with an unrelated future TD.

Since the ring is being traversed for the specific purpose of finding
a match with the current TD, always start from its first TRB. This is
the most reliable bit of information that we posses.

Tracking of HC's work progress is not affected, except for cases when
a misattributed event would have moved dequeue past a pending TD.

This replaces the custom while loop previously used within

Slightly modify 'xhci_free_segments_for_ring()' to handle lists
which do not loop. This makes it possible to use it in error
paths of 'xhci_alloc_segments_for_ring()'.

This change also prepares for switching the custom xhci linked segment

Slot ID is a index of a virtual device in struct 'xhci_hcd->devs[]'.
Previously, to get the slot ID associated with a port, we had to loop
through all devices and compare ports, which is very inefficient.
Instead, the slot ID (of the device which is directly connected to the
port), is added to the its corresponding 'xhci_port' struct. As a result,
finding the port's device is quick and easy.

Function 'xhci_find_slot_id_by_port()' is removed, as it is no longer
needed.

Variables real & fake port do not convey their purpose, thus they are
replaced with a pointer to the root hub port 'struct xhci_port *rhub_port'.
'rhub_port' contains real & fake ports in zero-based format, which happens
to be more widely used inside the xHCI driver:
 - 'real_port' is ('rhub_port->hw_portnum' + 1)
 - 'fake_port' is ('rhub_port->hcd_portnum' + 1)

One reason for real port being one-based, is to signal other functions in
case struct 'xhci_virt_device' initialization failed, in this case the
value will remain 0. This is no longer needed, instead we check whether
or not 'rhub_port' is 'NULL'.

xHC hardware needs to know which roothub port a USB device is attached to
when controlling the device, so the xHCI driver stores in each device the
roothub port which it's connected behind. This is done with two different
port index values, the 'real_port' which is an index to the xHC hardware
port register array, and the 'fake_port' which is the per hub port index
used by the hub driver.

Instead of finding real & fake port separately, find the root hub port
'xhci_port' structure which contains both real & fake port values:
    - 'real_port' is ('hw_portnum' + 1)
    - 'fake_port' is ('hcd_portnum' + 1)
i.e. real & fake port are 'hw_portnum' & 'hcd_portnum' in one-based
format.

The 'xhci_port' structure is a better way to refer to roothub ports than
the 'real_port' & 'fake_port'. As a result, these port indexes are slated
to be replaced with a direct pointer to the root hub port. This patch
setups the ground work for the future changes.

If a DiplayPort cable is directly connected to the host routers USB4
port, there is no tunnel involved but the port is in "redrive" mode
meaning that it is re-driving the DisplayPort signals from its
DisplayPort source. In this case we need to keep the domain powered on
otherwise once the domain enters D3cold the connected monitor blanks
too.

Since this happens only on Intel Barlow Ridge add a quirk that takes
runtime PM reference if we detect that the USB4 port entered redrive
mode (and release it once it exits the mode).

   - amba-pl011 serial driver fix for RS485 mode

   - stm32 serial driver fix for RS485 mode

  All of these have been in linux-next all week with no reported
  problems"

Pull x86 fixes from Borislav Petkov:

 - Make sure clearing CPU buffers using VERW happens at the latest
   possible point in the return-to-userspace path, otherwise memory
   accesses after the VERW execution could cause data to land in CPU
   buffers again

* tag 'x86_urgent_for_v6.8_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  KVM/VMX: Move VERW closer to VMentry for MDS mitigation
  KVM/VMX: Use BT+JNC, i.e. EFLAGS.CF to select VMRESUME vs. VMLAUNCH
  x86/bugs: Use ALTERNATIVE() instead of mds_user_clear static key
  x86/entry_32: Add VERW just before userspace transition
  x86/entry_64: Add VERW just before userspace transition
  x86/bugs: Add asm helpers for executing VERW

Pull irq fixes from Borislav Petkov:

 - Make sure GICv4 always gets initialized to prevent a kexec-ed kernel
   from silently failing to set it up

 - Do not call bus_get_dev_root() for the mbigen irqchip as it always
   returns NULL - use NULL directly

 - Fix hardware interrupt number truncation when assigning MSI
   interrupts

 - Correct sending end-of-interrupt messages to disabled interrupts
   lines on RISC-V PLIC

Pull erofs fix from Gao Xiang:

 - Fix page refcount leak when looking up specific inodes
   introduced by metabuf reworking
