commit ff712188daa3fe3ce7e11e530b4dca3826dae14a upstream.

When used on Huawei hisi platforms, Prolific Mass Storage Card Reader
which the VID:PID is in 067b:2731 might fail to enumerate at boot time
and doesn't work well with LPM enabled, combination quirks:
	USB_QUIRK_DELAY_INIT + USB_QUIRK_NO_LPM
fixed the problems.

commit 2b66ef84d0d2a0ea955b40bd306f5e3abbc5cf9c upstream.

The xHC resources allocated for USB devices are not released in correct
order after resuming in case when while suspend device was reconnected.

This issue has been detected during the fallowing scenario:
- connect hub HS to root port
- connect LS/FS device to hub port
- wait for enumeration to finish
- force host to suspend
- reconnect hub attached to root port
- wake host

For this scenario during enumeration of USB LS/FS device the Cadence xHC
reports completion error code for xHC commands because the xHC resources
used for devices has not been properly released.
XHCI specification doesn't mention that device can be reset in any order
so, we should not treat this issue as Cadence xHC controller bug.
Similar as during disconnecting in this case the device resources should
be cleared starting form the last usb device in tree toward the root hub.
To fix this issue usbcore driver should call hcd-&gt;driver-&gt;reset_device
for all USB devices connected to hub which was reconnected while
suspending.

commit 2240fed37afbcdb5e8b627bc7ad986891100e05d upstream.

Robert Morris created a test program which can cause
usb_hub_to_struct_hub() to dereference a NULL or inappropriate
pointer:

Oops: general protection fault, probably for non-canonical address

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.

We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

<title>USB: Add USB_QUIRK_NO_LPM quirk for sony xperia xz1 smartphone</title>

commit 159daf1258227f44b26b5d38f4aa8f37b8cca663 upstream.

The fastboot tool for communicating with Android bootloaders does not
work reliably with this device if USB 2 Link Power Management (LPM)
is enabled.

Various fastboot commands are affected, including the
following, which usually reproduces the problem within two tries:

  fastboot getvar kernel
  getvar:kernel  FAILED (remote: 'GetVar Variable Not found')

This issue was hidden on many systems up until commit 63a1f8454962
("xhci: stored cached port capability values in one place") as the xhci
driver failed to detect USB 2 LPM support if USB 3 ports were listed
before USB 2 ports in the "supported protocol capabilities".

Adding the quirk resolves the issue. No drawbacks are expected since
the device uses different USB product IDs outside of fastboot mode, and
since fastboot commands worked before, until LPM was enabled on the
tested system by the aforementioned commit.

Based on a patch from Forest &lt;forestix@nom.one&gt; from which most of the
code and commit message is taken.

<title>usb: core: fix pipe creation for get_bMaxPacketSize0</title>

commit 4aac0db5a0ebc599d4ad9bf5ebab78afa1f33e10 upstream.

When usb_control_msg is used in the get_bMaxPacketSize0 function, the
USB pipe does not include the endpoint device number. This can cause
failures when a usb hub port is reinitialized after encountering a bad
cable connection. As a result, the system logs the following error
messages:
usb usb2-port1: cannot reset (err = -32)
usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
usb usb2-port1: attempt power cycle
usb 2-1: new high-speed USB device number 5 using ci_hdrc
usb 2-1: device descriptor read/8, error -71

The problem began after commit 85d07c556216 ("USB: core: Unite old
scheme and new scheme descriptor reads"). There
usb_get_device_descriptor was replaced with get_bMaxPacketSize0. Unlike
usb_get_device_descriptor, the get_bMaxPacketSize0 function uses the
macro usb_rcvaddr0pipe, which does not include the endpoint device
number. usb_get_device_descriptor, on the other hand, used the macro
usb_rcvctrlpipe, which includes the endpoint device number.

By modifying the get_bMaxPacketSize0 function to use usb_rcvctrlpipe
instead of usb_rcvaddr0pipe, the issue can be resolved. This change will
ensure that the endpoint device number is included in the USB pipe,
preventing reinitialization failures. If the endpoint has not set the
device number yet, it will still work because the device number is 0 in
udev.

[  186.157858] tegra-xusb 3610000.usb: HC died; cleaning up
[  186.317280] tegra-xusb 3610000.usb: Timeout while waiting for evaluate context command

The issue is caused by disabling LPM on already suspended ports.

For USB2 LPM, the LPM is already disabled during port suspend. For USB3
LPM, port won't transit to U1/U2 when it's already suspended in U3,
hence disabling LPM is only needed for ports that are not suspended.

<title>usb: fix reference leak in usb_new_device()</title>

When device_add(&amp;udev-&gt;dev) succeeds and a later call fails,
usb_new_device() does not properly call device_del(). As comment of
device_add() says, 'if device_add() succeeds, you should call
device_del() when you want to get rid of it. If device_add() has not
succeeded, use only put_device() to drop the reference count'.

<title>usb: core: hcd: only check primary hcd skip_phy_initialization</title>

<content type='text'>
Before commit 53a2d95df836 ("usb: core: add phy notify connect and
disconnect"), phy initialization will be skipped even when shared hcd
doesn't set skip_phy_initialization flag. However, the situation is
changed after the commit. The hcd.c will initialize phy when add shared
hcd. This behavior is unexpected for some platforms which will handle phy
initialization by themselves. To avoid the issue, this will only check
skip_phy_initialization flag of primary hcd since shared hcd normally
follow primary hcd setting.

Pull driver core updates from Greg KH:
 "Here is a small set of driver core changes for 6.13-rc1.

  Nothing major for this merge cycle, except for the two simple merge
  conflicts are here just to make life interesting.

  Included in here are:

   - sysfs core changes and preparations for more sysfs api cleanups
     that can come through all driver trees after -rc1 is out

   - fw_devlink fixes based on many reports and debugging sessions

   - list_for_each_reverse() removal, no one was using it!

   - last-minute seq_printf() format string bug found and fixed in many
     drivers all at once.

   - minor bugfixes and changes full details in the shortlog"

* tag 'driver-core-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (35 commits)
  Fix a potential abuse of seq_printf() format string in drivers
  cpu: Remove spurious NULL in attribute_group definition
  s390/con3215: Remove spurious NULL in attribute_group definition
  perf: arm-ni: Remove spurious NULL in attribute_group definition
  driver core: Constify bin_attribute definitions
  sysfs: attribute_group: allow registration of const bin_attribute
  firmware_loader: Fix possible resource leak in fw_log_firmware_info()
  drivers: core: fw_devlink: Fix excess parameter description in docstring
  driver core: class: Correct WARN() message in APIs class_(for_each|find)_device()
  cacheinfo: Use of_property_present() for non-boolean properties
  cdx: Fix cdx_mmap_resource() after constifying attr in -&gt;mmap()
  drivers: core: fw_devlink: Make the error message a bit more useful
  phy: tegra: xusb: Set fwnode for xusb port devices
  drm: display: Set fwnode for aux bus devices
  driver core: fw_devlink: Stop trying to optimize cycle detection logic
  driver core: Constify attribute arguments of binary attributes
  sysfs: bin_attribute: add const read/write callback variants
