drivers/usb/gadget/function/f_fs.c:3829:8-15: WARNING opportunity for memdup_user
Use memdup_user rather than duplicating its implementation
This is a little bit restricted to reduce false positives

The current dwc3_gadget_reset_interrupt() will stop any active
transfers, but only addresses blocking of EP queuing for while we are
coming from a disconnected scenario, i.e. after receiving the disconnect
event. If the host decides to issue a bus reset on the device, the
connected parameter will still be set to true, allowing for EP queuing
to continue while we are disabling the functions. To avoid this, set the
connected flag to false until the stop active transfers is complete.

Add checks similar to dwc3_gadget_ep_queue() before kicking off
transfers after getting an endpoint completion event. Since cleaning
up completed requests will momentarily unlock dwc->lock, there is a
chance for a sequence like pullup disable to be executed. This can
lead to preparing a TRB, which will be removed by the pullup disable
routine.

Force-threaded interrupt handlers used to run with interrupts enabled,
something which could lead to deadlocks in case a threaded handler
shared a lock with code running in hard interrupt context (e.g. timer
callbacks) and did not explicitly disable interrupts.
Since commit 81e2073c175b ("genirq: Disable interrupts for force
threaded handlers") interrupt handlers always run with interrupts
disabled on non-RT so that drivers no longer need to do handle forced
threading ("threadirqs").
Drop the now obsolete workaround added by commit 63aea0dbab90 ("USB:
xhci: fix lock-inversion problem").

These were added in commit 780cc0f370 ("usb: gadget: add '__ref' for
rndis_config_register() and cdc_config_register()") to silence
modpost, but they didn't fix the real problem - that was fixed later
by removing wrong __init annotations in commit c94e289f195e ("usb:
gadget: remove incorrect __init/__exit annotations").
It really never makes sense for a function to be marked __ref unless
it (1) has some conditional that chooses whether to call an __init
function (or access __initdata) or not and (2) has a comment
explaining why the __ref is there and why it is safe.

Currently user can configure UAC1 function with
parameters that violate UAC1 spec or are not supported
by UAC1 gadget implementation.
This can lead to incorrect behavior if such gadget
is connected to the host - like enumeration failure
or other issues depending on host's UAC1 driver
implementation, bringing user to a long hours
of debugging the issue.
Instead of silently accept these parameters, throw
an error if they are not valid.

for some sequence of operations required for Xilinx USB controllers.
This driver is also used to choose between PIPE clock coming from SerDes
and the Suspend Clock. Before the controller is out of reset, the clock
selection should be changed to PIPE clock in order to make the USB
controller work. There is a register added in Xilinx USB controller
register space for the same.

Select USB_GADGET Kconfig option in order to fix build failure which
happens because ChipIdea driver has a build dependency on both USB_GADGET
and USB_EHCI_HCD, while USB_EHCI_TEGRA force-selects the ChipIdea driver
without taking into account the tristate USB_GADGET dependency. It's not
possible to do anything about the cyclic dependency of the Kconfig
options, but USB_EHCI_TEGRA is now a deprecated option that isn't used
by defconfigs and USB_GADGET is wanted on Tegra by default, hence it's
okay to have a bit clunky workaround for it.

Revert commit 44cc89f76464 ("PM: runtime: Update device status
before letting suppliers suspend") that introduced a race condition
into __rpm_callback() which allowed a concurrent rpm_resume() to
run and resume the device prematurely after its status had been
changed to RPM_SUSPENDED by __rpm_callback().
Fixes: 44cc89f76464 ("PM: runtime: Update device status before letting suppliers suspend")

Pull drm fixes from Dave Airlie:
"Regular fixes pull, pretty small set of fixes, a couple of i915 and
amdgpu, one ttm, one nouveau and one omap. Probably smaller than usual
for this time, so we'll see if something pops up next week or if this
will continue to stay small.
Summary:
ttm:
- Make ttm_bo_unpin() not wraparound on too many unpins
omap:
- Fix coccicheck warning in omap
amdgpu:
- DCN 3.0 gamma fixes
- DCN 2.1 corrupt screen fix
i915:
- Workaround async flip + VT-d frame corruption on HSW/BDW
- Fix NMI watchdog crash due to uninitialized OA buffer use on gen12+
nouveau:
- workaround oops with bo syncing"

The underlying problem is not introduced by the commit, yet it uncovered the
underlying issue. The cited commit relies on valid pages. This is not given for
due to some bugs. For now, just warn and work around the issue by just ignoring
the bad ttm objects.
