Deferred probe is an expected return value for fwnode_usb_role_switch_get().
Given that the driver deals with it properly, there's no need to output a

The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
These hubs suffer from two separate problems:
1) After the host system was suspended and woken up, the hubs appear to
be in a random state. Some downstream ports (both internal to the
built-in audio and network controllers, and external to USB sockets)
may no longer be functional. The exact list of disabled ports (if
any) changes from wakeup to wakeup. Ports remain in that state until
the dock is power-cycled, or until the laptop is rebooted.
Wakeup sources connected to the hubs (keyboard, WoL on the integrated
gigabit controller) will wake the system up from suspend, but they
may no longer work after wakeup (and in that case will no longer work
as wakeup source in a subsequent suspend-wakeup cycle).
This issue appears in the logs with messages such as:
usb 1-6.1-port4: cannot disable (err = -71)
usb 1-6-port2: cannot disable (err = -71)
usb 1-6.1: clear tt 1 (80c0) error -71
usb 1-6-port4: cannot disable (err = -71)
usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71

usb 1-6.1-port1: cannot disable (err = -71)

usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
usb 1-6.1-port1: cannot disable (err = -71)
2) Some USB devices cannot be enumerated properly. So far I have only
seen the issue with USB 3.0 devices. The same devices work without
problem directly connected to the host system, to other systems or to
other hubs (even when those hubs are connected to the OneLink+ dock).
One very reliable reproducer is this USB 3.0 HDD enclosure:
152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius
I have seen it happen sporadically with other USB 3.0 enclosures,
with controllers from different manufacturers, all self-powered.
Typical messages in the logs:
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 6, error -62

usb 2-1.4: device not accepting address 7, error -62

xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 9, error -62
usb 2-1-port4: unable to enumerate USB device
Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved
the second issue. Further testing then uncovered the first issue. Test
results are summarized in this table:
=======================================================================================
Settings USB2 hotplug USB3 hotplug State after waking up
---------------------------------------------------------------------------------------
power/control=auto works fails broken
usbcore.autosuspend=-1 works works broken
OR power/control=on
power/control=auto works (1) works (1) works
and USB_QUIRK_RESET_RESUME
power/control=on works works works
and USB_QUIRK_RESET_RESUME
HUB_QUIRK_DISABLE_AUTOSUSPEND works works works
and USB_QUIRK_RESET_RESUME
=======================================================================================
In those results, the power/control settings are applied to both hubs,
both on the USB2 and USB3 side, before each test.
From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs
properly after a suspend-wakeup cycle, and the hubs must not autosuspend
to work around the USB3 issue.
A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs'
upstream links from suspending (the downstream ports can still suspend).
This secondary effect is used in results (1). It is enough to solve the
USB3 problem.
Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that
solves both issues.
Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via
the kernel command line for over a year without noticing any side
effect.
Thanks to Oliver Neukum @Suse for explanations of the operations of
USB_QUIRK_RESET_RESUME, and requesting more testing.

In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.
Note that this is found by KMSAN, so only kernel compilation
is tested.

* tag 'i2c-for-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:

MAINTAINERS: remove Nehal Shah from AMD MP2 I2C DRIVER
i2c: imx: If pm_runtime_get_sync() returned 1 device access is possible
The "hmem" platform-devices that are created to represent the
platform-advertised "Soft Reserved" memory ranges end up inserting a
resource that causes the iomem_resource tree to look like this:
340000000-43fffffff : hmem.0
340000000-43fffffff : Soft Reserved
340000000-43fffffff : dax0.0
This is because insert_resource() reparents ranges when they completely
intersect an existing range.
This matters because code that uses region_intersects() to scan for a
given IORES_DESC will only check that top-level 'hmem.0' resource and
not the 'Soft Reserved' descendant.
So, to support EINJ (via einj_error_inject()) to inject errors into
memory hosted by a dax-device, be sure to describe the memory as
IORES_DESC_SOFT_RESERVED. This is a follow-on to:
commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP")
...that fixed EINJ support for "Soft Reserved" ranges in the first
instance.
Fixes: 262b45ae3ab4 ("x86/efi: EFI soft reservation to E820 enumeration")

to assembler defined symbols, which regressed as a result of:
commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1")
In that commit, I allude to restoring debug info for assembler defined

Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2.
Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g
specified in order for -gsplit-dwarf to work at all.
-gsplit-dwarf has been mutually exclusive with -g since support for
CONFIG_DEBUG_INFO_SPLIT was introduced in
commit 866ced950bcd ("kbuild: Support split debug info v4")
I don't think it ever needed to be.
