The DWC3_EP_RESOURCE_ALLOCATED flag ensures that the resource of an
endpoint is only assigned once. Unless the endpoint is reset, don't
clear this flag. Otherwise we may set endpoint resource again, which
prevents the driver from initiate transfer after handling a STALL or
endpoint halt to the control endpoint.

fsl_ep_queue() is only called by usb_ep_queue() (as ep->ops->queue()).
So _ep isn't NULL.
As ep->ops->queue = fsl_ep_queue, the ep was initialized by
struct_ep_setup() and so ep->udc isn't NULL either.
Drop the check for _ep being NULL and assign udc earlier to prevent
following an uninitialized pointer in the two dev_vdbg()s in lines 878
and 882. This fixes a compiler warning when using clang and

When ncm function is working and then stop usb0 interface for link down,
eth_stop() is called. At this piont, accidentally if usb transport error
should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled.
After that, ncm_disable() is called to disable for ncm unbind
but gether_disconnect() is never called since 'in_ep' is not enabled.
As the result, ncm object is released in ncm unbind
but 'dev->port_usb' associated to 'ncm->port' is not NULL.
And when ncm bind again to recover netdev, ncm object is reallocated
but usb0 interface is already associated to previous released ncm object.
Therefore, once usb0 interface is up and eth_start_xmit() is called,
released ncm object is dereferrenced and it might cause use-after-free memory.
[function unlink via configfs]
usb0: eth_stop dev->port_usb=ffffff9b179c3200
--> error happens in usb_ep_enable().
NCM: ncm_disable: ncm=ffffff9b179c3200
--> no gether_disconnect() since ncm->port.in_ep->enabled is false.
NCM: ncm_unbind: ncm unbind ncm=ffffff9b179c3200
NCM: ncm_free: ncm free ncm=ffffff9b179c3200 <-- released ncm
[function link via configfs]

eth_start_xmit()
--> dev->wrap()
Unable to handle kernel paging request at virtual address dead00000000014f
This patch addresses the issue by checking if 'ncm->netdev' is not NULL at
ncm_disable() to call gether_disconnect() to deassociate 'dev->port_usb'.
It's more reasonable to check 'ncm->netdev' to call gether_connect/disconnect
rather than check 'ncm->port.in_ep->enabled' since it might not be enabled
but the gether connection might be established.

Off-by-one errors happen because nr_snk_pdo and nr_src_pdo are
incorrectly added one. The index of the loop is equal to the number of
PDOs to be updated when leaving the loop and it doesn't need to be added
one.
When doing the power negotiation, TCPM relies on the "nr_snk_pdo" as
the size of the local sink PDO array to match the Source capabilities
of the partner port. If the off-by-one overflow occurs, a wrong RDO
might be sent and unexpected power transfer might happen such as over
voltage or over current (than expected).
"nr_src_pdo" is used to set the Rp level when the port is in Source
role. It is also the array size of the local Source capabilities when
filling up the buffer which will be sent as the Source PDOs (such as
in Power Negotiation). If the off-by-one overflow occurs, a wrong Rp
level might be set and wrong Source PDOs will be sent to the partner
port. This could potentially cause over current or port resets.

The pointer from a xhci usb virt device to its root hub port
(vdev->rhub_port) is set later when device is addressed, not while
vdev is allocated.
Tracepoints dereferenced this rhub_port pointer when freeing the virt
device, which causes null pointer dereference if tracing is enabled
and device is freed before addressed.
This can happen if tracing is enabled and xhci driver is unloaded before
a device is fully enumerated, or initial enumeration fails and device
is reset and freed before retry.
Don't dereference the rhub_port or show port numbers when tracing
xhci_free_virt_device(). This info is not very useful anyway.
Print the more useful slot id instead

The show and store callback routines for the "disable" sysfs attribute
file in port.c acquire the device lock for the port's parent hub
device. This can cause problems if another process has locked the hub
to remove it or change its configuration:
Removing the hub or changing its configuration requires the
hub interface to be removed, which requires the port device
to be removed, and device_del() waits until all outstanding
sysfs attribute callbacks for the ports have returned. The
lock can't be released until then.
But the disable_show() or disable_store() routine can't return
until after it has acquired the lock.
The resulting deadlock can be avoided by calling
sysfs_break_active_protection(). This will cause the sysfs core not
to wait for the attribute's callback routine to return, allowing the
removal to proceed. The disadvantage is that after making this call,
there is no guarantee that the hub structure won't be deallocated at
any moment. To prevent this, we have to acquire a reference to it
first by calling hub_get().

This removes the need to probe for the quirk.

If the device is configured for system wakeup, then make sure that the
xHCI driver knows about it and make sure to permit wakeup only at the
appropriate time.
For host mode, if the controller goes through the dwc3 code path, then a
child xHCI platform device is created. Make sure the platform device
also inherits the wakeup setting for xHCI to enable remote wakeup.
For device mode, make sure to disable system wakeup if no gadget driver
is bound. We may experience unwanted system wakeup due to the wakeup
signal from the controller PMU detecting connection/disconnection when
in low power (D3). E.g. In the case of Steam Deck, the PCI PME prevents
the system staying in suspend.

Among the attribute file callback routines in
drivers/usb/core/sysfs.c, the interface_authorized_store() function is
the only one which acquires a device lock on an ancestor device: It
calls usb_deauthorize_interface(), which locks the interface's parent
USB device.
The will lead to deadlock if another process already owns that lock
and tries to remove the interface, whether through a configuration
change or because the device has been disconnected. As part of the
removal procedure, device_del() waits for all ongoing sysfs attribute
callbacks to complete. But usb_deauthorize_interface() can't complete
until the device lock has been released, and the lock won't be
released until the removal has finished.
The mechanism provided by sysfs to prevent this kind of deadlock is
to use the sysfs_break_active_protection() function, which tells sysfs
not to wait for the attribute callback.

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function ljca_auxdev_release
calls kfree(auxdev->dev.platform_data) to free the parameter data
of the function ljca_new_client_device. The callers of
ljca_new_client_device shouldn't call kfree() again
in the error handling path to free the platform data.
Fix this by cleaning up the redundant kfree() in all callers and
adding kfree() the passed in platform_data on errors which happen
before auxiliary_device_init() succeeds .

When orientation switch is enabled in ucsi glink, there is a xhci
probe failure seen when booting up in host mode in reverse
orientation.
During bootup the following things happen in multiple drivers:
a) DWC3 controller driver initializes the core in device mode when the
dr_mode is set to DRD. It relies on role_switch call to change role to
host.
b) QMP driver initializes the lanes to TYPEC_ORIENTATION_NORMAL as a
normal routine. It relies on the typec_switch_set call to get notified
of orientation changes.
c) UCSI core reads the UCSI_GET_CONNECTOR_STATUS via the glink and
provides initial role switch to dwc3 controller.
When booting up in host mode with orientation TYPEC_ORIENTATION_REVERSE,
then we see the following things happening in order:
a) UCSI gives initial role as host to dwc3 controller ucsi_register_port.
Upon receiving this notification, the dwc3 core needs to program GCTL from
PRTCAP_DEVICE to PRTCAP_HOST and as part of this change, it asserts GCTL
Core soft reset and waits for it to be completed before shifting it to
host. Only after the reset is done will the dwc3_host_init be invoked and
xhci is probed. DWC3 controller expects that the usb phy's are stable
during this process i.e., the phy init is already done.
b) During the 100ms wait for GCTL core soft reset, the actual notification
from PPM is received by ucsi_glink via pmic glink for changing role to
host. The pmic_glink_ucsi_notify routine first sends the orientation
change to QMP and then sends role to dwc3 via ucsi framework. This is
happening exactly at the time GCTL core soft reset is being processed.
c) When QMP driver receives typec switch to TYPEC_ORIENTATION_REVERSE, it
then re-programs the phy at the instant GCTL core soft reset has been
asserted by dwc3 controller due to which the QMP PLL lock fails in
qmp_combo_usb_power_on.
d) After the 100ms of GCTL core soft reset is completed, the dwc3 core
goes for initializing the host mode and invokes xhci probe. But at this
point the QMP is non-responsive and as a result, the xhci plat probe fails
during xhci_reset.
Fix this by passing orientation switch to available ucsi instances if
their gpio configuration is available before ucsi_register is invoked so
that by the time, the pmic_glink_ucsi_notify provides typec_switch to QMP,
the lane is already configured and the call would be a NOP thus not racing
with role switch.

In the scenario of entering hibernation with udisk in the system, if the
udisk was gone or resume fail in the thaw phase of hibernation. Its state
will be set to NOTATTACHED. At this point, usb_hub_wq was already freezed
and can't not handle disconnect event. Next, in the poweroff phase of
hibernation, SYNCHRONIZE_CACHE SCSI command will be sent to this udisk
when poweroff this scsi device, which will cause uas_submit_urbs to be
called to submit URB for sense/data/cmd pipe. However, these URBs will
submit fail as device was set to NOTATTACHED state. Then, uas_submit_urbs
will return a value SCSI_MLQUEUE_DEVICE_BUSY to the caller. That will lead
the SCSI layer go into an ugly loop and system fail to go into hibernation.
On the other hand, when we specially check for -ENODEV in function
uas_queuecommand_lck, returning DID_ERROR to SCSI layer will cause device
poweroff fail and system shutdown instead of entering hibernation.
To fix this issue, let uas_submit_urbs to return original generic error
when submitting URB failed. At the same time, we need to translate -ENODEV
to DID_NOT_CONNECT for the SCSI layer.

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
