Here is a warning report about lack of registered release()
from kobject lib:
Device '(null)' does not have a release() function, it is broken and must be fixed.
WARNING: CPU: 0 PID: 48430 at drivers/base/core.c:2332 device_release+0x104/0x120

When regulator_register() returns fail and directly goto `clean` symbol,
rdev->dev has not registered release() function yet (which is registered
by regulator_class in the following), so rdev needs to be freed manually.
If rdev->dev.of_node is not NULL, which means the of_node has gotten by
regulator_of_get_init_data(), it needs to call of_node_put() to avoid
refcount leak.
Otherwise, only calling put_device() would lead memory leak of rdev
in further:

This is same scheme as fixed-regulator.
Without that property used, the parent regulator can be shut down (if not an always on).
Thus leading to inappropriate behavior:

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.
This series adds support for the regulators found in MT6331 and MT6332
main/companion PMICs.
Adding support to each driver in each subsystem is done in different
patch series as to avoid spamming uninteresting patches to maintainers.
Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

On recent kernels, the PM8058 L16 (or any other PM8058 LDO-regulator)
does not come up if they are supplied by an SMPS-regulator. This
is not very strange since the regulators are registered in a long
array and the L-regulators are registered before the S-regulators,
and if an L-regulator defers, it will never get around to registering
the S-regulator that it needs.
See arch/arm/boot/dts/qcom-apq8060-dragonboard.dts:
pm8058-regulators {
(...)
vdd_l13_l16-supply = <&pm8058_s4>;
(...)
Ooops.
Fix this by moving the PM8058 S-regulators first in the array.
Do the same for the PM8901 S-regulators (though this is currently
not causing any problems with out device trees) so that the pattern
of registration order is the same on all PMnnnn chips.

By using a ratio of delay to poll_enabled_time that is not integer
time_remaining underflows and does not exit the loop as expected.
As delay could be derived from DT and poll_enabled_time is defined
in the driver this can easily happen.
Use a signed iterator to make sure that the loop exits once
the remaining time is negative.

For RPMH regulators it doesn't make sense to indicate
regulator-allow-set-load without saying what modes you can switch to,
so be sure to indicate a dependency on regulator-allowed-modes.
In general this is true for any regulators that are setting modes
instead of setting a load directly, for example RPMH regulators. A
counter example would be RPM based regulators, which set a load
change directly instead of a mode change. In the RPM case
regulator-allow-set-load alone is sufficient to describe the regulator
(the regulator can change its output current, here's the new load),
but in the RPMH case what valid operating modes exist must also be
stated to properly describe the regulator (the new load is this, what
is the optimum mode for this regulator with that load, let's change to
that mode now).
With this in place devicetree validation can catch issues like this:
/mnt/extrassd/git/linux-next/arch/arm64/boot/dts/qcom/sm8350-hdk.dtb: pm8350-rpmh-regulators: ldo5: 'regulator-allowed-modes' is a dependency of 'regulator-allow-set-load'
From schema: /mnt/extrassd/git/linux-next/Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.yaml
Where the RPMH regulator hardware is described as being settable, but
there are no modes described to set it to!

-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.
commit 258fafcd06 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit 21f9c8a13b ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.
The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.
Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

staging: r8188eu: add firmware dependency
to the core framework. We had to revert out a commit that affected boot
on some devices that have the CLK_OPS_PARENT_ENABLE flag set. It isn't
critical to have that fix so we'll try again next time.
Driver side fixes include:
- Plug an of node refcount bug in the TI clk driver
- Fix the error handling in the raspberry pi firmware get_rate
so that errors don't look like valid frequencies
- Avoid going out of bounds in the raspberry pi driver too if the
video firmware returns something we're not expecting

The mmap lock protects the page walker from changes to the page tables
during the walk. However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.
For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.
For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.
This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging. As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

Now acpi_os_ioremap() is marked with __init because it calls memblock_
is_memory() which is also marked with __init in the !ARCH_KEEP_MEMBLOCK
case. However, acpi_os_ioremap() is called by ordinary functions such
as acpi_os_{read, write}_memory() and causes section mismatch warnings:
WARNING: modpost: vmlinux.o: section mismatch in reference: acpi_os_read_memory (section: .text) -> acpi_os_ioremap (section: .init.text)
WARNING: modpost: vmlinux.o: section mismatch in reference: acpi_os_write_memory (section: .text) -> acpi_os_ioremap (section: .init.text)
Fix these warnings by selecting ARCH_KEEP_MEMBLOCK unconditionally and
removing the __init modifier of acpi_os_ioremap(). This can also give a
chance to track "memory" and "reserved" memblocks after early boot.

Commit 8ba62d3794 ("task_work: Call tracehook_notify_signal from
get_signal on all architectures") adjust arch_do_signal_or_restart() for
all architectures. LoongArch hasn't been upstream yet at that time and
can be still built successfully without adjustment because this function
has a weak version with the correct prototype. It is obviously that we
should convert LoongArch to use new API, otherwise some signal handlings
will be lost.

Ensure that all input sections are listed explicitly in the linker
script, and issue a warning otherwise. This ensures that the binary
image matches the PE/COFF and other image metadata exactly, which is
important for things like code signing.

Pull io_uring fixes from Jens Axboe:
- A single fix for over-eager retries for networking (Pavel)
- Revert the notification slot support for zerocopy sends.
It turns out that even after more than a year or development and
testing, there's not full agreement on whether just using plain
ordered notifications is Good Enough to avoid the complexity of using
the notifications slots. Because of that, we decided that it's best
left to a future final decision.
We can always bring back this feature, but we can't really change it
or remove it once we've released 6.0 with it enabled. The reverts
leave the usual CQE notifications as the primary interface for
knowing when data was sent, and when it was acked. (Pavel)
