The UDC is not a suitable parent of the net device as the UDC can
change or vanish during the lifecycle of the ethernet gadget. This
can be illustrated with the following:
mkdir -p /sys/kernel/config/usb_gadget/mygadget
cd /sys/kernel/config/usb_gadget/mygadget
mkdir -p configs/c.1/strings/0x409
echo "C1:Composite Device" > configs/c.1/strings/0x409/configuration
mkdir -p functions/ecm.usb0
ln -s functions/ecm.usb0 configs/c.1/
echo "dummy_udc.0" > UDC
rmmod dummy_hcd
The 'rmmod' removes the UDC from the just created gadget, leaving
the still existing net device with a no longer existing parent.
Accessing the ethernet device with commands like:
ip --details link show usb0
will result in a KASAN splat:

Instead of manipulating musb->xceiv->otg->state directly, use the newly
introduced musb_get_state() and musb_set_state() inline functions.
Later, these inline functions will be modified to get rid of the

It is since ages perfectly possible to compile both of these
modules into the same kernel, which makes no sense since it
is one piece of hardware.
Compile one module named "fotg210.ko" for both HCD and UDC
drivers by collecting the init calls into a fotg210-core.c
file and start to centralize things handling one and the same
piece of hardware.
Stub out the initcalls if one or the other part of the driver
was not selected.
Tested by compiling one or the other or both of the drivers
into the kernel and as modules.

The Faraday FOTG210 is a dual-mode OTG USB controller that can
act as host, peripheral or both. To be able to probe from one
hardware description and to follow the pattern of other dual-
mode controllers such as MUSB or MTU3 we need to collect the
two, currently completely separate drivers in the same
directory.
After this, users need to select the main symbol USB_FOTG210
and then each respective subdriver. We pave the road to
compile both drivers into the same kernel and select the
one we want to use at probe() time, and possibly add OTG
support in the end.
This patch doesn't do much more than create the new symbol
and collect the drivers in one place. We also add a comment
for the section of dual-mode controllers in the Kconfig
file so people can see what these selections are about.
Also add myself as maintainer as there has been little
response on my patches to these drivers.

In ast_vhub_epn_handle_ack() when the received data length exceeds the
buffer, it does not check the case and just copies to req.buf and cause
a buffer overflow, kernel oops on this case.
This issue could be reproduced on a BMC with an OS that enables the
lan over USB:
1. In OS, enable the usb eth dev, verify it pings the BMC OK;
2. In OS, set the usb dev mtu to 2000. (Default is 1500);
3. In OS, ping the BMC with `-s 2000` argument.
The BMC kernel will get oops with below logs:

When a broken USB accessory connects to a USB host, usbcore might
keep doing enumeration retries. If the host has a watchdog mechanism,
the kernel panic will happen on the host.
This patch provides an attribute early_stop to limit the numbers of retries
for each port of a hub. If a port was marked with early_stop attribute,
unsuccessful connection attempts will fail quickly. In addition, if an
early_stop port has failed to initialize, it will ignore all future
connection events until early_stop attribute is clear.

When the TRB ring is full, the dwc3 driver must make sure that there's
at least 1 TRB with Interrupt On Completion (IOC) set to notify of
available TRBs.
The current logic just sets the TRB's IOC whenever we run out of TRBs,
but it doesn't consider that there may be other TRBs with IOC/LST set
already. This creates more events and unnecessary delay from interrupt
handling. Only forcefully set IOC when we run out of TRBs and none of
the TRBs in the TRB ring has had IOC set.

Since this driver is using the "gpio-usb-b-connector"

It has been pointed out that the kernel log messages warning about
problems in USB configuration and related descriptors are vexing for
users. The warning log level has a fairly high priority, but the user
can do nothing to fix the underlying errors in the device's firmware.
To reduce the amount of useless information produced by tools that
filter high-priority log messages, we can change these warnings to
notices, i.e., change dev_warn() to dev_notice(). The same holds for
a few messages that currently use dev_err(): Unless they indicate a
failure that might make a device unusable (such as inability to
transfer a config descriptor), change them to dev_notice() also.

Merge tag 'random-6.1-rc3-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator fix from Jason Donenfeld:
"One fix from Jean-Philippe Brucker, addressing a regression in which
early boot code on ARM64 would use the non-_early variant of the
arch_get_random family of functions, resulting in the architectural
random number generator appearing unavailable during that early phase
of boot.
The fix simply changes arch_get_random*() to arch_get_random*_early().
This distinction between these two functions is a bit of an old wart
I'm not a fan of, and for 6.2 I'll see if I can make obsolete the
_early variant, so that one function does the right thing in all
contexts without overhead"

powerpc/64s: Disable preemption in hash lazy mmu mode
powerpc/64s: make linear_map_hash_lock a raw spinlock
powerpc/64s: make HPTE lock and native_tlbie_lock irq-safe
powerpc/64s: Add lockdep for HPTE lock
powerpc/pseries: Use lparcfg to reconfig VAS windows for DLPAR CPU
powerpc/pseries/vas: Add VAS IRQ primary handler
Currently the return value of 'sub_driver->init' is not checked. If
sparse_keymap_setup() called in the init function fails, 'generic_
inputdev' is freed, then it will lead a UAF when using it in generic_
acpi_laptop_init(). Fix it by checking the return value and setting
generic_inputdev to NULL after free, so as to avoid double free it.
The error code in generic_subdriver_init() is always negative, so the
return of generic_subdriver_init() can be simplified.

Some laptops don't support SW_LID, but still have backlight control,
move backlight resuming before SW_LID event handling so as to avoid
backlight mistake due to early return.

Not all compilers support declare variables in switch-case, so move
declarations to the beginning of a function. Otherwise we may get such
build errors:

The current LoongArch kernel stack is padded as if obeying the MIPS o32
calling convention (32 bytes), signifying the port's MIPS lineage but no
longer making sense. Remove the padding for clarity.
