This prevents use of this driver with ACPI via PRP0001 and
is an example of an anti pattern I'm trying to remove from
the kernel. Hence drop from this driver.
Also switch of.h for mod_devicetable.h include given use of
struct of_device_id which is defined in that header.

pmbus_write_smbalert_mask() ignores the errors if the chip can't set
smbalert mask the standard way. It is not necessarily a problem for the irq
support if the chip is otherwise properly setup but it may leave an
uncleared fault behind.
pmbus_core will pick the fault on the next register_check(). The register
check will fails regardless of the actual register support by the chip.
This leads to missing attributes or debugfs entries for chips that should
provide them.
We cannot rely on register_check() as PMBUS_SMBALERT_MASK may be read-only.
Unconditionally clear the page fault after setting PMBUS_SMBALERT_MASK to
avoid the problem.

Use _pmbus_read_byte_data() rather than calling smbus directly to check

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/acpi to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

acpi_dev_hid_match() does not check for adev == NULL, dereferencing
it unconditional.
Add a check for adev being NULL before calling acpi_dev_hid_match().
At the moment acpi_quirk_skip_serdev_enumeration() is never called with
a controller_parent without an ACPI companion, but better safe than sorry.

The Vexia EDU ATLA 10 tablet (9V version) which shipped with Android 4.2
as factory OS has the usual broken DSDT issues for x86 Android tablets.
On top of that this tablet is special because all its LPSS island
peripherals are enumerated as PCI devices rather then as ACPI devices as
they typically are.
For the x86-android-tablets kmod to be able to instantiate a serdev client
for the Bluetooth HCI on this tablet, an ACPI_QUIRK_UART1_SKIP quirk is
necessary.
Modify acpi_dmi_skip_serdev_enumeration() to work with PCI enumerated
UARTs without an UID, such as the UARTs on this tablet.
Also make acpi_dmi_skip_serdev_enumeration() exit early if there are no
quirks, since there is nothing to do then.
And add the necessary quirks for the Vexia EDU ATLA 10 tablet.
This should compile with CONFIG_PCI being unset without issues because
dev_is_pci() is defined as "(false)" then.

The qcom-cpucp mailbox irq is expected to function during suspend-resume
cycle particularly when the scmi cpufreq driver can query the current
frequency using the get_level message after the cpus are brought up during

failures we see during resume.

The commit 8396c793ffdf ("mmc: dw_mmc: Fix IDMAC operation with pages
bigger than 4K") increased the max_req_size, even for 4K pages, causing
various issues:
- Panic booting the kernel/rootfs from an SD card on Rockchip RK3566
- Panic booting the kernel/rootfs from an SD card on StarFive JH7100
- "swiotlb buffer is full" and data corruption on StarFive JH7110
At this stage no fix have been found, so it's probably better to just
revert the change.

It turns out that the Allwinner A100/A133 SoC only supports 8K DMA
blocks (13 bits wide), for both the SD/SDIO and eMMC instances.
And while this alone would make a trivial fix, the H616 falls back to
the A100 compatible string, so we have to now match the H616 compatible
string explicitly against the description advertising 64K DMA blocks.
As the A100 is now compatible with the D1 description, let the A100
compatible string point to that block instead, and introduce an explicit
match against the H616 string, pointing to the old description.
Also remove the redundant setting of clk_delays to NULL on the way.

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.

The kTLS tx handling code is using a mix of get_page() and
page_ref_inc() APIs to increment the page reference. But on the release
path (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.
This is an issue when using pages from large folios: the get_page()
references are stored on the folio page while the page_ref_inc()
references are stored directly in the given page. On release the folio
page will be dereferenced too many times.
This was found while doing kTLS testing with sendfile() + ZC when the
served file was read from NFS on a kernel with NFS large folios support
(commit 49b29a573da8 ("nfs: add support for large folios")).

The referenced commits introduced a two-step process for deleting FTEs:
- Lock the FTE, delete it from hardware, set the hardware deletion function
to NULL and unlock the FTE.
- Lock the parent flow group, delete the software copy of the FTE, and
remove it from the xarray.
However, this approach encounters a race condition if a rule with the same
match value is added simultaneously. In this scenario, fs_core may set the
hardware deletion function to NULL prematurely, causing a panic during
subsequent rule deletions.
To prevent this, ensure the active flag of the FTE is checked under a lock,
which will prevent the fs_core layer from attaching a new steering rule to
an FTE that is in the process of deletion.

The number of PCI vectors allocated by the platform (which may be fewer
than requested) is currently not honored when creating the SF pool;
only the PCI MSI-X capability is considered.
As a result, when a platform allocates fewer vectors
(in non-dynamic mode) than requested, the PF and SF pools end up
with an invalid vector range.
This causes incorrect SF vector accounting, which leads to the
following call trace when an invalid IRQ vector is allocated.
This issue is resolved by ensuring that the platform's vector
limit is respected for both the SF and PF pools.

IB representors depend on ETH representors, so the IB representors
should not exist without the ETH ones. When unloading the ETH
representors, the corresponding IB representors should be also
unloaded.
The commit 8d159eb2117b ("RDMA/mlx5: Use IB set_netdev and get_netdev functions")
introduced the use of the ib_device_set_netdev API in IB
repsresentors. ib_device_set_netdev() increments the refcount of
the representor's netdev when loading an IB representor and
decrements it when unloading.
Without the unloading of the IB representor, the refcount of the
representor's netdev remains greater than 0, preventing it from
being unregistered.
The patch uncovered an underlying bug where the eth representor is
unloaded, without unloading the IB representor.
This issue happened when using multiport E-switch and rebooting,
causing the shutdown to hang when unloading the ETH representor
because the refcount of the representor's netdevice was greater than 0.
Call trace:
unregister_netdevice: waiting for eth3 to become free. Usage count = 2

[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.
[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer

The NVMe 2.0 specification adds an independent identify namespace
data structure that contains generic attributes that apply to all
namespace types. Some attributes carry over from the NVM command set
identify namespace data structure, and others are new.
Currently, the data structure only considered when CRIMS is enabled or
when the namespace type is key-value.
However, the independent namespace data structure is mandatory for
devices that implement features from the 2.0+ specification. Therefore,
we can check this data structure first. If unavailable, retrieve the
generic attributes from the NVM command set identify namespace data
structure.
