Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.10-rc1.
Nothing hugely earth-shattering, just constant forward progress for
hardware support of new devices and cleanups over the drivers.
Included in here are:
- Thunderbolt / USB 4 driver updates
- typec driver updates
- dwc3 driver updates
- gadget driver updates
- uss720 driver id additions and fixes (people use USB->arallel port
devices still!)
- onboard-hub driver rename and additions for new hardware
- xhci driver updates
- other small USB driver updates and additions for quirks and api
changes
All of these have been in linux-next for a while with no reported
problems"

The recently introduced commit '635ce0db8956 ("soc: qcom: pmic_glink:
don't traverse clients list without a lock")' ensured that the clients
list is not modified while traversed.
But the callback is made from the GLINK IRQ handler and as such this
mutual exclusion can not be provided by a (sleepable) mutex.
Replace the mutex with a spinlock.
Fixes: 635ce0db89 ("soc: qcom: pmic_glink: don't traverse clients list without a lock")

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The PMIC GLINK service runs on one of the co-processors of some modern
Qualcomm platforms and implements USB-C and battery managements. It uses
a message based protocol over GLINK for communication with the OS, hence
the name.
The driver implemented provides the rpmsg device for communication and
uses auxiliary bus to spawn off individual devices in respective
subsystem. The auxiliary devices are spawned off from a
platform_device, so that the drm_bridge is available early, to allow the
DisplayPort driver to probe even before the remoteproc has spun up.
