The arguments to queue_trb are always byteswapped to LE for placement in
the ring, but this should not happen in the case of immediate data; the
bytes copied out of transfer_buffer are already in the correct order.
Add a complementary byteswap so the bytes end up in the ring correctly.
This was observed on BE ppc64 with a "Texas Instruments TUSB73x0
SuperSpeed USB 3.0 xHCI Host Controller [104c:8241]" as a ch341
usb-serial adapter ("1a86:7523 QinHeng Electronics HL-340 USB-Serial
adapter") always transmitting the same character (generally NUL) over
the serial link regardless of the key pressed.

commit ef513be0a9 ("usb: xhci: Add Clear_TT_Buffer") schedules work
to clear TT buffer, but causes a use-after-free regression at the same time
Make sure hub_tt_work finishes before endpoint is disabled, otherwise
the work will dereference already freed endpoint and device related
pointers.
This was triggered when usb core failed to read the configuration
descriptor of a FS/LS device during enumeration.
xhci driver queued clear_tt_work while usb core freed and reallocated
a new device for the next enumeration attempt.
EHCI driver implents ehci_endpoint_disable() that makes sure
clear_tt_work has finished before it returns, but xhci lacks this support.
usb core will call hcd->driver->endpoint_disable() callback before
disabling endpoints, so we want this in xhci as well.
The added xhci_endpoint_disable() is based on ehci_endpoint_disable()

A recent info-leak bug manifested itself along with warning about a
negative buffer overflow:
ldusb 1-1:0.28: Read buffer overflow, -131383859965943 bytes dropped
when it was really a rather large positive one.
A sanity check that prevents this has now been put in place, but let's
fix up the size format specifiers, which should all be unsigned.

The custom ring-buffer implementation was merged without any locking or
explicit memory barriers, but a spinlock was later added by commit
9d33efd9a7 ("USB: ldusb bugfix").
The lock did not cover the update of the tail index once the entry had
been processed, something which could lead to memory corruption on
weakly ordered architectures or due to compiler optimisations.
Specifically, a completion handler running on another CPU might observe
the incremented tail index and update the entry before ld_usb_read() is
done with it.

Endpoints with a maxpacket length of 0 are probably useless. They
can't transfer any data, and it's not at all unlikely that an HCD will
crash or hang when trying to handle an URB for such an endpoint.
Currently the USB core does not check for endpoints having a maxpacket
value of 0. This patch adds a check, printing a warning and skipping
over any endpoints it catches.
Now, the USB spec does not rule out endpoints having maxpacket = 0.
But since they wouldn't have any practical use, there doesn't seem to
be any good reason for us to accept them.

composite_dev_cleanup call from the failure of configfs_composite_bind
frees up the cdev->os_desc_req and cdev->req. If the previous calls of
bind and unbind is successful these will carry stale values.
Consider the below sequence of function calls:
configfs_composite_bind()
composite_dev_prepare()
- Allocate cdev->req, cdev->req->buf
composite_os_desc_req_prepare()
- Allocate cdev->os_desc_req, cdev->os_desc_req->buf
configfs_composite_unbind()
composite_dev_cleanup()
- free the cdev->os_desc_req->buf and cdev->req->buf
Next composition switch
configfs_composite_bind()
- If it fails goto err_comp_cleanup will call the
composite_dev_cleanup() function
composite_dev_cleanup()
- calls kfree up with the stale values of cdev->req->buf and
cdev->os_desc_req from the previous configfs_composite_bind
call. The free call on these stale values leads to double free.
Hence, Fix this issue by setting request and buffer pointer to NULL after
kfree.

nbd requires socket families to support the shutdown method so the nbd
recv workqueue can be woken up from its sock_recvmsg call. If the socket
does not support the callout we will leave recv works running or get hangs
later when the device or module is removed.
This adds a check during socket connection/reconnection to make sure the
socket being passed in supports the needed callout.

This driver is using regulator_get_optional() to handle all the supplies
that it handles, and only ever enables and disables all supplies en masse
without ever doing any other configuration of the device to handle missing
power. These are clear signs that the API is being misused - it should only
be used for supplies that may be physically absent from the system and in
these cases the hardware usually needs different configuration if the
supply is missing. Instead use normal regualtor_get(), if the supply is
not described in DT then the framework will substitute a dummy regulator in
so no special handling is needed by the consumer driver.
In the case of the PHY regulator the handling in the driver is a hack to
deal with integrated PHYs; the supplies are only optional in the sense
that that there's some confusion in the code about where they're bound to.
From a code point of view they function exactly as normal supplies so can
be treated as such. It'd probably be better to model this by instantiating
a PHY object for integrated PHYs.

This was preceded by us timing out everything and shutting down the
sockets for the device. The problem is we had a request in the queue at
the same time, so we completed the request twice. This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.
Fix this by checking cmd->status in nbd_read_stat. We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.
For the clear_req cause this is initiated by the user, so again is safe.

Merge tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules fixes from Jessica Yu:
- Revert __ksymtab_$namespace.$symbol naming scheme back to
__ksymtab_$symbol, as it was causing issues with depmod.
Instead, have modpost extract a symbol's namespace from __kstrtabns
and __ksymtab_strings.
- Fix `make nsdeps` for out of tree kernel builds (make O=...) caused
by unescaped '/'.
Use a different sed delimiter to avoid this problem.
* tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
scripts/nsdeps: use alternative sed delimiter
symbol namespaces: revert to previous __ksymtab name scheme
modpost: make updating the symbol namespace explicit
modpost: delegate updating namespaces to separate function
A slightly larger set of fixes have accrued in the last two weeks.
Mostly a collection of the usual smaller fixes:
- Marvell Armada: USB phy setup issues on Turris Mox
- Broadcom: GPIO/pinmux DT mapping corrections for Stingray, MMC bus
width fix for RPi Zero W, GPIO LED removal for RPI CM3. Also some
maintainer updates.
- OMAP: Fixlets for display config, interrupt settings for wifi, some
clock/PM pieces. Also IOMMU regression fix and a ti-sysc no-watchdog
regression fix.
- i.MX: A few fixes around PM/settings, some devicetree fixlets and
catching up with config option changes in DRM
- Rockchip: RockRro64 misc DT fixups, Hugsun X99 USB-C, Kevin display
panel settings
... and some smaller fixes for Davinci (backlight, McBSP DMA), Allwinner
(phy regulators, PMU removal on A64, etc).
