The added #ifdefs in the PM rework were almost correct, but still
cause warnings in some randconfig builds:
drivers/usb/host/xhci-tegra.c:2147:12: error: 'tegra_xusb_resume' defined but not used [-Werror=unused-function]
2147 | static int tegra_xusb_resume(struct device *dev)

drivers/usb/host/xhci-tegra.c:2105:12: error: 'tegra_xusb_suspend' defined but not used [-Werror=unused-function]
2105 | static int tegra_xusb_suspend(struct device *dev)
Replace the #ifdef checks with simpler __maybe_unused annotations to
reliably shut up these warnings.

For the situation that the disconnect event comes very late when the
device is unplugged, the driver would resubmit the RX bulk transfer
after getting the callback with -EPROTO immediately and continually.
Finally, soft lockup occurs.
This patch avoids to resubmit RX immediately. It uses a workqueue to
schedule the RX NAPI. And the NAPI would resubmit the RX. It let the
disconnect event have opportunity to stop the submission before soft
lockup.

Currently, the UVC function is activated when open on the corresponding
v4l2 device is called. On another open the activation of the function
fails since the deactivation counter in `usb_function_activate` equals
0. However the error is not returned to userspace since the open of the
v4l2 device is successful.
On a close the function is deactivated (since deactivation counter still
equals 0) and the video is disabled in `uvc_v4l2_release`, although the
UVC application potentially is streaming.
Move activation of UVC function to subscription on UVC_EVENT_SETUP
because there we can guarantee for a userspace application utilizing
UVC. Block subscription on UVC_EVENT_SETUP while another application
already is subscribed to it, indicated by `bool func_connected` in
`struct uvc_device`. Extend the `struct uvc_file_handle` with member
`bool is_uvc_app_handle` to tag it as the handle used by the userspace
UVC application.
With this a process is able to check capabilities of the v4l2 device
without deactivating the function for the actual UVC application.

The reason for this problem is that irq has been disabled in
machine_restart() and then it calls down_interruptible() in
virt_efi_reset_system(), which would occur sleep in irq context,
it is dangerous! Commit 99409b935c9a("locking/semaphore: Add
might_sleep() to down_*() family") add might_sleep() in
down_interruptible(), so the bug info is here. down_trylock()
can solve this problem, cause there is no might_sleep.

Now that Kees Cook has added a definition for HCS_N_PORTS_MAX in
commit 72dd1843232c ("USB: EHCI: Add register array bounds to HCS
ports"), the code in ehci_hub_control() which sanitizes port index
values can be improved a little.
The idea behind this change is that it prevents a possible
out-of-bounds pointer computation, which the compiler might be able to
detect since the port_status[] array now has a fixed length rather
than a variable length.

Saeed Mahameed says:
====================
mlx5-updates-2021-10-04
Misc updates for mlx5 driver
1) Add TX max rate support for MQPRIO channel mode
2) Trivial TC action and modify header refactoring
3) TC support for accept action in fdb offloads
4) Allow single IRQ for PCI functions
5) Bridge offload: Pop PVID VLAN header on egress miss
Vlad Buslov says:
=================
With current architecture of mlx5 bridge offload it is possible for a
packet to match in ingress table by source MAC (resulting VLAN header push
in case of port with configured PVID) and then miss in egress table when
destination MAC is not in FDB. Due to the lack of hardware learning in
NICs, this, in turn, results packet going to software data path with PVID
VLAN already added by hardware. This doesn't break software bridge since it
accepts either untagged packets or packets with any provisioned VLAN on
ports with PVID, but can break ingress TC, if affected part of Ethernet
header is matched by classifier.
Improve compatibility with software TC by restoring the packet header on
egress miss. Effectively, this change implements atomicity of mlx5 bridge
offload implementation - packet is either modified and redirected to
destination port or appears unmodified in software.

The commit 217504a05532 ("usb: typec: ucsi: Work around PPM
losing change information") had solved this issue
previously, but in a really complex manner. The core issue
is that on some platforms the EC firmware does not interrupt
the driver on unplug event in some cases, mainly when the
cable is unplugged immediately after the plug-in.
From now on handling that problem by simply re-checking new

UCSI does not tell the driver explicitly when the firmware
(PPM in UCSI lingo) has actually detected the partner
alternate modes, there is no specific change event for that.
That's why they have to be checked with any notification
that informs that PD contract with that partner has been
achieved.
Previously the alternate modes were checked always when the
firmware (PPM) informed that something with the partner had
changed, but on some platforms the EC firmware does not
generate separate events for generic partner changes at all.
On those platforms the EC firmware notifies the driver only
about connections, or separately about the PD contract if it
was not achieved soon enough after the initial connection
event.

The "poll worker" that is introduced here is first used for
checking partner alternate modes, but it can later be used
for any partner task that requires a separate job to be
scheduled to the connector specific workqueues.
The mechanism allows the partner device specific tasks to be
polling tasks and also delayed tasks if necessary.
By polling the partner alternate modes with this mechanism
the long command completion timeout value can be reduced
back to normal. The long command completion timeout was only
used to work around a problem on some platforms where the EC
firmware (PPM) didn't return BUSY even when it should with
the alt mode commands.

The USB2.0 spec chapter 11.24.2.13 says that the USB port which is going
under test needs to be put in suspend state before sending the test
command. Many hubs, don't enforce this precondition and they work fine
without this step. But there are some "special" hubs, which requires to
disable the port power before sending the test command.
Because the USB spec mention that the port should be suspended, also
do this step before sending the test command. This could rise the
problem with other hubs which are not compliant with the spec and the
test command will not work if the port is suspend. If such hubs are
found, a similar workaround like the disable part could be implemented
to skip the suspend port command.

Check ethernet controller DT node for "mdio" subnode and use it with

PHY devices in a standard DT based way.
This is required for BCM53573 SoC support. That family is sometimes
called Northstar (by marketing?) but is quite different from it. It uses
different CPU(s) and many different hw blocks.
One of shared blocks in BCM53573 is Ethernet controller. Switch however
is not SRAB accessible (as it Northstar) but is MDIO attached.

It allows describing for example a fixed link. It's more accurate than
just guessing there may be one (depending on a chipset).
2. Verify PHY ID before trying to connect PHY

connected as MDIO devices instead of a real PHY. Don't try connecting to

'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller'
and 'MIPS Common Device Memory Map' which are present in some MIPS related
boards. There is already bindings documentation for these two located in:
- Documentation/devicetree/bindings/power/mti,mips-cpc.yaml
- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml
Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

The value to adjust in the bridge register RALINK_PCI_IOBASE must take into
account the raw value from DT, not only the translated linux port number.
As long as io_offset is zero, the two are the same, but if you were to use
multiple host bridge in the system, or pick a different bus address in DT,
you can have a nonzero io_offset. At this means to take into account the
bus address which is used to calculate this offset, substracting it from
the IO resource start address.

pci_remap_iospace() was originally meant as an architecture specific helper
but it moved into generic code after all architectures had the same

The way for doing this will be using a macro 'pci_remap_iospace' defined
for those architectures that need a special treatment. Hence, put core API
function inside preprocesor conditional code for 'pci_remap_iospace'

We need to cast the pointer, unlike memcpy() eth_hw_addr_set()
does not take void *. The driver already casts &port->mac_addr
to u8 * in other places.

The problem is that "mac_id" is a u32 so this check for underflow does
not work when "mac_id" is zero. In that situation, "mac_id - 1" is
UINT_MAX instead of -1 so the condition is true. It leads to an
array underflow on the next line.

The comparison against SIZE_MAX produces a harmless warning on 64-bit
architectures:
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:185:16: error: result of comparison of constant 419244183493398898 with expression of type 'unsigned int' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (num_pages > (SIZE_MAX - sizeof(struct pagelist) -
~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shut up that warning by adding a cast to a longer type.
