ad408a1596 Revert "usb: dwc2: host: Setting qtd to NULL after freeing it"
This reverts commit b0d659022e.

The reverted commit does nothing but adding two unnecessary lines
of code.  It sets a local variable to NULL in two functions, but
that variable is not used anywhere in the rest of those functions.
This is just confusing, so let's remove it.

d78cc1a4b7 usb: gadget: net2272: remove redundant assignments to pointer 's'
The pointer 's' is being assigned however the pointer is
never used with either of these values before it it reassigned much
later on.  I suspect it was going to be used in the output of the
main control registers scnprintf but was omitted.  The assignments
of 's' to the driver name or the literal string are redundant and
can be removed.

508595515f usb: gadget: Zero ffs_io_data
In some cases the "Allocate & copy" block in ffs_epfile_io() is not
executed. Consequently, in such a case ffs_alloc_buffer() is never called
and struct ffs_io_data is not initialized properly. This in turn leads to
problems when ffs_free_buffer() is called at the end of ffs_epfile_io().

This patch uses kzalloc() instead of kmalloc() in the aio case and memset()
in non-aio case to properly initialize struct ffs_io_data.

4833a94eb3 usb: gadget: f_fs: data_len used before properly set
The following line of code in function ffs_epfile_io is trying to set
flag io_data->use_sg in case buffer required is larger than one page.

    io_data->use_sg = gadget->sg_supported && data_len > PAGE_SIZE;

However at this point of time the variable data_len has not been set
to the proper buffer size yet. The consequence is that io_data->use_sg
is always set regardless what buffer size really is, because the condition
(data_len > PAGE_SIZE) is effectively an unsigned comparison between
-EINVAL and PAGE_SIZE which would always result in TRUE.

c846b03ff7 USB: dwc2: Don't turn off the usbphy in suspend if wakeup is enabled
If the 'snps,need-phy-for-wake' is set in the device tree then:

- We know that we can wakeup, so call device_set_wakeup_capable().
  The USB core will use this knowledge to enable wakeup by default.
- We know that we should keep the PHY on during suspend if something
  on our root hub needs remote wakeup.  This requires the patch (USB:
  Export usb_wakeup_enabled_descendants()).  Note that we don't keep
  the PHY on at suspend time if it's not needed because it would be a
  power draw.

If we later find some users of dwc2 that can support wakeup without
keeping the PHY on we may want to add a way to call
device_set_wakeup_capable() without keeping the PHY on at suspend
time.

066cfd0770 usb: gadget: dwc2: fix zlp handling
The patch 10209abe87
usb: dwc2: gadget: Add scatter-gather mode

avoided a NULL pointer dereference (hs_ep->req == NULL) by
calling dwc2_gadget_fill_nonisoc_xfer_dma_one() directly instead of through
the dwc2_gadget_config_nonisoc_xfer_ddma() wrapper, which unconditionally
dereferenced the said pointer.

However, this was based on an incorrect assumption that in the context of
dwc2_hsotg_program_zlp() the pointer is always NULL, which is not the case.
The result were SB CV MSC tests failing starting from Test Case 6.

Instead, this patch reverts to calling the wrapper and adds a check for
the pointer being NULL inside the wrapper.

babd183915 usb: dwc2: host: Fix wMaxPacketSize handling (fix webcam regression)
In commit abb621844f ("usb: ch9: make usb_endpoint_maxp() return
only packet size") the API to usb_endpoint_maxp() changed.  It used to
just return wMaxPacketSize but after that commit it returned
wMaxPacketSize with the high bits (the multiplier) masked off.  If you
wanted to get the multiplier it was now up to your code to call the
new usb_endpoint_maxp_mult() which was introduced in
commit 541b6fe630 ("usb: add helper to extract bits 12:11 of
wMaxPacketSize").

Prior to the API change most host drivers were updated, but no update
was made to dwc2.  Presumably it was assumed that dwc2 was too
simplistic to use the multiplier and thus just didn't support a
certain class of USB devices.  However, it turns out that dwc2 did use
the multiplier and many devices using it were working quite nicely.
That means that many USB devices have been broken since the API
change.  One such device is a Logitech HD Pro Webcam C920.

Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it
did call usb_maxpacket() which in turn called usb_endpoint_maxp().

Let's update dwc2 to work properly with the new API.

812086d362 USB: move usb debugfs directory creation to the usb common core
The USB gadget subsystem wants to use the USB debugfs root directory, so
move it to the common "core" USB code so that it is properly initialized
and removed as needed.

In order to properly do this, we need to load the common code before the
usb core code, when everything is linked into the kernel, so reorder the
link order of the code.

Also as the usb common code has the possibility of the led trigger logic
to be merged into it, handle the build option properly by only having
one module init/exit function and have the common code initialize the
led trigger if needed.

ef513be0a9 usb: xhci: Add Clear_TT_Buffer
USB 2.0 specification chapter 11.17.5 says "as part of endpoint halt
processing for full-/low-speed endpoints connected via a TT, the host
software must use the Clear_TT_Buffer request to the TT to ensure
that the buffer is not in the busy state".

In our case, a full-speed speaker (ConferenceCam) is behind a high-
speed hub (ConferenceCam Connect), sometimes once we get STALL on a
request we may continue to get STALL with the folllowing requests,
like Set_Interface.

Here we invoke usb_hub_clear_tt_buffer() to send Clear_TT_Buffer
request to the hub of the device for the following Set_Interface
requests to the device to get ACK successfully.

4998f1efd1 usb: Add devaddr in struct usb_device
The Clear_TT_Buffer request sent to the hub includes the address of
the LS/FS child device in wValue field. usb_hub_clear_tt_buffer()
uses udev->devnum to set the address wValue. This won't work for
devices connected to xHC.

For other host controllers udev->devnum is the same as the address of
the usb device, chosen and set by usb core. With xHC the controller
hardware assigns the address, and won't be the same as devnum.

Here we add devaddr in "struct usb_device" for
usb_hub_clear_tt_buffer() to use.

bd21f0222a USB: Fix chipmunk-like voice when using Logitech C270 for recording audio.
This patch fixes the chipmunk-like voice that manifets randomly when
using the integrated mic of the Logitech Webcam HD C270.

The issue was solved initially for this device by commit 2394d67e44
("USB: add RESET_RESUME for webcams shown to be quirky") but it was then
reintroduced by e387ef5c47 ("usb: Add USB_QUIRK_RESET_RESUME for all
Logitech UVC webcams"). This patch is to have the fix back.

c8a93dcd0c USB: atm: ueagle-atm.c: remove redundant license text
Now that we have the correct SPDX tag for the ueagle-atm.c file, the
wall of "boiler-plate" text is not needed.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

5e456a9263 USB: atm: ueagle-atm.c: fix SPDX tag to be BSD2
Thomas rightly points out that I got the BSD clause count wrong for this
driver, it should be 2, not 3 based on the text in the license here, so
fix that up.

He also raises the question that the license text points to a v2 only
license, yet the text in the header says "or later".  Given that the
text in the header says "or later" and all of the other USB atm drivers
are licensed in that way, I am going to leave the string as-is for that
mark.

3ea3091f1b usbip: usbip_host: fix stub_dev lock context imbalance regression
Fix the following sparse context imbalance regression introduced in
a patch that fixed sleeping function called from invalid context bug.

kbuild test robot reported on:

Regressions in current branch:

drivers/usb/usbip/stub_dev.c:399:9: sparse: sparse: context imbalance in 'stub_probe' - different lock contexts for basic block
drivers/usb/usbip/stub_dev.c:418:13: sparse: sparse: context imbalance in 'stub_disconnect' - different lock contexts for basic block
drivers/usb/usbip/stub_dev.c:464:1-10: second lock on line 476

Error ids grouped by kconfigs:

This is a real problem in an error leg where spin_lock() is called on an
already held lock.

Fix the imbalance in stub_probe() and stub_disconnect().
