The ucsi_psy_get_current_max function defaults to 0.1A when it is not
clear how much current the partner device can support. But this does
not check the port is connected, and will report 0.1A max current when
nothing is connected. Update ucsi_psy_get_current_max to report 0A when
there is no connection.

e4f5ce9908 usb: gadget: f_eem: Fix memory leak in eem_unwrap
The existing code did not handle the failure case of usb_ep_queue in the
command path, potentially leading to memory leaks.

Improve error handling to free all allocated resources on usb_ep_queue
failure. This patch continues to use goto logic for error handling, as the
existing error handling is complex and not easily adaptable to auto-cleanup
helpers.

40f8d17eed drivers/usb/dwc3: fix PCI parent check
The sysdev_is_parent check was being used to infer PCI devices that have
the DMA mask set from the PCI capabilities, but sysdev_is_parent is also
used for non-PCI ACPI devices in which case the DMA mask would be the
bus default or as set by the _DMA method.

Without this fix the DMA mask would default to 32-bits and so allocation
would fail if there was no DRAM below 4GB.

41e99fe200 usb: storage: Fix memory leak in USB bulk transport
A kernel memory leak was identified by the 'ioctl_sg01' test from Linux
Test Project (LTP). The following bytes were mainly observed: 0x53425355.

When USB storage devices incorrectly skip the data phase with status data,
the code extracts/validates the CSW from the sg buffer, but fails to clear
it afterwards. This leaves status protocol data in srb's transfer buffer,
such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can
lead to USB protocols leaks to user space through SCSI generic (/dev/sg*)
interfaces, such as the one seen here when the LTP test requested 512 KiB.

Fix the leak by zeroing the CSW data in srb's transfer buffer immediately
after the validation of devices that skip data phase.

Note: Differently from CVE-2018-1000204, which fixed a big leak by zero-
ing pages at allocation time, this leak occurs after allocation, when USB
protocol data is written to already-allocated sg pages.

8c13a7323b xhci: sideband: Fix race condition in sideband unregister
Uttkarsh Aggarwal observed a kernel panic during sideband un-register
and found it was caused by a race condition between sideband unregister,
and creating sideband interrupters.
The issue occurrs when thread T1 runs uaudio_disconnect() and released
sb->xhci via sideband_unregister, while thread T2 simultaneously accessed
the now-NULL sb->xhci in xhci_sideband_create_interrupter() resulting in
a crash.

Ensure new endpoints or interrupter can't be added to a sidenband after
xhci_sideband_unregister() cleared the existing ones, and unlocked the
sideband mutex.
Reorganize code so that mutex is only taken and released once in
xhci_sideband_unregister(), and clear sb->vdev while mutex is taken.

Use mutex guards to reduce human unlock errors in code

Refuse to add endpoints or interrupter if sb->vdev is not set.
sb->vdev is set when sideband is created and registered.

f6bb3b67be xhci: dbgtty: Fix data corruption when transmitting data form DbC to host
Data read from a DbC device may be corrupted due to a race between
ongoing write and write request completion handler both queuing new
transfer blocks (TRBs) if there are remining data in the kfifo.

TRBs may be in incorrct order compared to the data in the kfifo.

Driver fails to keep lock between reading data from kfifo into a
dbc request buffer, and queuing the request to the transfer ring.

This allows completed request to re-queue itself in the middle of
an ongoing transfer loop, forcing itself between a kfifo read and
request TRB write of another request

cpu0					cpu1 (re-queue completed req2)

lock(port_lock)
dbc_start_tx()
kfifo_out(fifo, req1->buffer)
unlock(port_lock)
					lock(port_lock)
					dbc_write_complete(req2)
					dbc_start_tx()
      					kfifo_out(fifo, req2->buffer)
					unlock(port_lock)
					lock(port_lock)
					req2->trb = ring->enqueue;
					ring->enqueue++
					unlock(port_lock)
lock(port_lock)
req1->trb = ring->enqueue;
ring->enqueue++
unlock(port_lock)

In the above scenario a kfifo containing "12345678" would read "1234" to
req1 and "5678" to req2, but req2 is queued before req1 leading to
data being transmitted as "56781234"

Solve this by adding a flag that prevents starting a new tx if we
are already mid dbc_start_tx() during the unlocked part.

The already running dbc_do_start_tx() will make sure the newly completed
request gets re-queued as it is added to the request write_pool while
holding the lock.

b69dfcab68 xhci: fix stale flag preventig URBs after link state error is cleared
A usb device caught behind a link in ss.Inactive error state needs to
be reset to recover. A VDEV_PORT_ERROR flag is used to track this state,
preventing new transfers from being queued until error is cleared.

This flag may be left uncleared if link goes to error state between two
resets, and print the following message:

"xhci_hcd 0000:00:14.0: Can't queue urb, port error, link inactive"

Fix setting and clearing the flag.

The flag is cleared after hub driver has successfully reset the device
when hcd->reset_device is called. xhci-hcd issues an internal "reset
device" command in this callback, and clear all flags once the command
completes successfully.

This command may complete with a context state error if slot was recently
reset and is already in the defauilt state. This is treated as a success
but flag was left uncleared.

The link state field is also unreliable if port is currently in reset,
so don't set the flag in active reset cases.
Also clear the flag immediately when link is no longer in ss.Inactive
state and port event handler detects a completed reset.

This issue was discovered while debugging kernel bugzilla issue 220491.
It is likely one small part of the problem, causing some of the failures,
but root cause remains unknown

1ec39d2cd8 usb: cdns3: Fix double resource release in cdns3_pci_probe
The driver uses pcim_enable_device() to enable the PCI device,
the device will be automatically disabled on driver detach through
the managed device framework. The manual pci_disable_device() calls
in the error paths are therefore redundant and should be removed.

Found via static anlaysis and this is similar to commit 99ca0b57e4
("thermal: intel: int340x: processor: Fix warning during module unload").

baeb66fbd4 usb: gadget: udc: fix use-after-free in usb_gadget_state_work
A race condition during gadget teardown can lead to a use-after-free
in usb_gadget_state_work(), as reported by KASAN:

  BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0
  Workqueue: events usb_gadget_state_work

The fundamental race occurs because a concurrent event (e.g., an
interrupt) can call usb_gadget_set_state() and schedule gadget->work
at any time during the cleanup process in usb_del_gadget().

Commit 399a45e523 ("usb: gadget: core: flush gadget workqueue after
device removal") attempted to fix this by moving flush_work() to after
device_del(). However, this does not fully solve the race, as a new
work item can still be scheduled *after* flush_work() completes but
before the gadget's memory is freed, leading to the same use-after-free.

This patch fixes the race condition robustly by introducing a 'teardown'
flag and a 'state_lock' spinlock to the usb_gadget struct. The flag is
set during cleanup in usb_del_gadget() *before* calling flush_work() to
prevent any new work from being scheduled once cleanup has commenced.
The scheduling site, usb_gadget_set_state(), now checks this flag under
the lock before queueing the work, thus safely closing the race window.

The issue occurs because usbhs_sys_function_pullup(), which accesses the IP
registers, is executed after the USBHS clocks have been disabled. The
problem is reproducible on the Renesas RZ/G3S SoC starting with the
addition of module stop in the clock enable/disable APIs. With module stop
functionality enabled, a bus error is expected if a master accesses a
module whose clock has been stopped and module stop activated.

Disable the IP clocks at the end of remove.

53abe3e1c1 sched: Remove never used code in mm_cid_get()
Clang is not happy with set but unused variable (this is visible
with `make W=1` build:

  kernel/sched/sched.h:3744:18: error: variable 'cpumask' set but not used [-Werror,-Wunused-but-set-variable]

It seems like the variable was never used along with the assignment
that does not have side effects as far as I can see.  Remove those
altogether.

73ba88fb04 firewire: init_ohci1394_dma: add missing function parameter documentation
Add missing kernel-doc parameter descriptions for five functions
in init_ohci1394_dma.c to fix documentation warnings when building
with W=1.

This patch addresses the following warnings:
- init_ohci1394_wait_for_busresets: missing @ohci description
- init_ohci1394_enable_physical_dma: missing @ohci description
- init_ohci1394_reset_and_init_dma: missing @ohci description
- init_ohci1394_controller: missing @num, @slot, @func descriptions
- setup_ohci1394_dma: missing @opt description

Tested with GCC 13.2.0 and W=1 flag. All documentation warnings
for these functions have been resolved.

   of view (we only care about the SQPOLL thread itself), and vastly
   overkill as only the systime was used. On top of that, also be a bit
