Add the AC and DC power limit definitions for the ASUS ROG Strix SCAR 16
2025 (G635LX), enabling the nv_tgp, nv_dynamic_boost and ppt_pl*_* tuning
attributes on this model. Without an entry in the power_limits table the
attributes are not exposed (has_valid_limit() returns false) and the
firmware power knobs cannot be controlled.
The G635LX ships an NVIDIA RTX 5090 Laptop GPU (150 W base TGP + 25 W
Dynamic Boost = 175 W max, per the ASUS specification) and an Intel Core
Ultra 9 275HX, matching the ROG Strix SCAR 18 (G835LW). The limits are
therefore taken from the G835LW sibling entry and the ASUS specification
rather than dumped from this board's firmware.
Testing on a G635LX confirmed the attributes populate with this entry and
that writing nv_dynamic_boost changes the measured GPU power draw
(~151 W at minimum, ~169 W at maximum during inference), i.e. the limits
reach firmware.

The HP OMEN MAX 16-ak0xxx (board ID: 8DD6) has the same WMI interface
as other Victus S boards, but requires quirks for correctly switching
thermal profile.
After testing we know that (similar to another HP Omen Max 16 device,
board ID 8D87), the embedded controller on this board does not expose
thermal profile which means we have to intentionally disable EC readback.
Add the DMI board name to victus_s_thermal_profile_boards[] table and
map it to omen_v1_no_ec_thermal_params.
Testing on board 8DD6 confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.

Newer Huawei laptops (e.g. FLMH-XX / MateBook 14 2024) no longer support
the legacy WMI interface for Fn-lock control. Instead, they expose direct
ACPI methods \GFRS and \SFRS (Get/Set Fn key Reversal Status) which
communicate with the EC via registers 0x6B (read) and 0x6C (write).
Add huawei_acpi_fn_lock_get() and huawei_acpi_fn_lock_set() helpers that
use acpi_evaluate_object() to call these methods. Both
huawei_wmi_fn_lock_get() and huawei_wmi_fn_lock_set() now probe for
\GFRS/\SFRS via acpi_has_method() first and fall back to the legacy WMI
path if not present.
Tested on: HUAWEI FLMH-XX (MateBook 14 2024),
CachyOS (kernel 7.0.9-1-cachyos).

The pnp.device_class string in the ACPI companion of the platform
device used for binding the driver is never initialized, so passing
it to acpi_bus_generate_netlink_event() is effectively equivalent to
passing an empty string literal to that function.

hsmp_parse_acpi_table() published sock->dev before hsmp_read_acpi_crs()
had mapped virt_base_addr. sock->dev is the readiness gate for the
lock-free data plane, so on a multi-socket system - where socket 0
exposes /dev/hsmp before later sockets finish probing - an ioctl aimed
at a socket still in bring-up could pass the gate and dereference a NULL
virt_base_addr.
Publish sock->dev last with smp_store_release() once virt_base_addr, the
mailbox offsets and the semaphore are initialized, and read it with
smp_load_acquire() in hsmp_send_message() so a non-NULL dev guarantees
the rest of the socket state is visible.

hsmp_read_acpi_crs() and hsmp_read_acpi_dsd() read the ACPI handle and
emit error messages via sock->dev. Pass the struct device explicitly to
both helpers instead of reading it back from sock->dev.
This is a pure refactor with no functional change; it prepares for
publishing sock->dev as the data-plane readiness gate only after the
socket has been fully initialized, so the parsers must not depend on
sock->dev already being set.

The .driver_data member of the the two struct ssam_device_id arrays were
initialized by list expressions. This isn't easily readable if you don't
work with the Surface System Aggregator core regularily. Using named
initializers is more explicit and thus easier to parse and also more
robust to changes of the struct definition. This robustness is relevant
for a planned change to struct ssam_device_id replacing .driver_data
by an anonymous union.
This change doesn't introduce changes to the compiled ssam_device_id
arrays.

MSI Claw devices produce WMI events through the MSI WMI hotkeys GUID for
some of their buttons. When pressed, these cause spam in the kernel. For
the majority of devices these events can be safely ignored as they are
duplicated by the AT Translated Set 2 Keyboard device exposed as an
evdev. For the MSI Claw A8 BZ2EM model's M-Center Menu button (left of
the screen) there is no associated keyboard event, so this event must be
exposed. Map this button to the same scancode produced by the AT
Keyboard device on other models. This does cause double F15 events on
the A1M, 7 AI+ A2VM, and 8 AI+ A2VM, but it appears to be harmless in my
testing.

Update the con_id for the Sony IMX471 sensor to "vana" to serve as the

associated with the IMX471 image sensor, have been identified on Lenovo

PMFW reports the S0i3 subsystem accounting per SoC, and the set of IP
blocks and their bit ordering differ across SoC generations. Family
1Ah, Model 80h accounts for a distinct set of 19 IP blocks, which does
not match the ordering in soc15_ip_blk[].
Commit 043af31c8d30 ("platform/x86/amd/pmc: Add PMC driver support for
AMD 1Ah M80H SoC") wired amd_1ah_m80_cpu_info to soc15_ip_blk[], so
M80H has been reporting incorrect S0i3 accounting via debugfs.
Add soc15_ip_blk_v3[] with the correct ordering and point
amd_1ah_m80_cpu_info at it.

The previously integrated power limits for the ASUS ROG Strix G16 G614PR
laptop model were incorrect and too low compared to the windows counterparts.
Update the power limits to the correct specifications based on the
platform's hardware capabilities:
- Increase AC PL1/SPL max limit from 90W to 120W.
- Increase AC PL2/SPPT default/max from 110W/125W to 140W/145W.
- Increase AC PL3/FPPT default/max from 110W/125W to 140W/145W.

cpu_feature_enabled() is the one to use to test feature flags so hide
the static thing which doesn't pay attention to disabled mask bits
anyway.
Use the following command to do the replacement:
$ git grep --files-with-matches -w static_cpu_has -- ':(exclude)*cpufeature.h' \
| xargs sed -i 's/static_cpu_has(/cpu_feature_enabled\(/g'
There should be no functional changes resulting from this.

On models flagged with requires_fan_curve in the DMI power_data table
(30 entries), the BIOS ACPI method SPLX only writes PPT values to the
EC when the fan mode is set to Manual (FANM=4). FANM is set to 4 by
the DEFC method when a custom fan curve is written. Without an active
custom fan curve, the WMI DEVS call returns success but the firmware
silently ignores the PPT value, so userspace observes no effect from
its write.
Gate writes to ASUS_WMI_DEVID_PPT_{PL1_SPL,PL2_SPPT,PL3_FPPT,APU_SPPT,
PLAT_SPPT} on a check of asus_wmi_custom_fan_curve_is_enabled(), and
return -EBUSY with a pr_warn_once() when no fan curve is active on an
affected model. Export the helper from asus-wmi so asus-armoury can
call it across module boundaries.

The driver registers two distinct WMI devices: a control device
(BITLAND_WMI_CONTROL) and an event device (BITLAND_WMI_EVENT). During
the probe phase, the event device handling path returns early before
initializing the platform profile device (data->pp_dev), leaving it
NULL.
However, the PM sleep operations are registered globally for the WMI
driver and are triggered for both devices. When entering suspend, the
event device invokes bitland_mifs_wmi_suspend(), which passes the
uninitialized data->pp_dev (NULL) into laptop_profile_get(). This leads
to a NULL pointer dereference inside dev_get_drvdata(), causing a
kernel Oops and halting the suspend sequence.
Fix this by adding a validity check for data->pp_dev in both the suspend
and resume callbacks, safely skipping profile operations for the event
device.

dmi_get_system_info(...) can return NULL. Using that as %s arguments
of dev_info() would log "(null)" (as part of a message like
'... System Vendor: "(null)", Product Name: "(null)" ...'), which may
be confusing for users.
Use Elvis operator to print "(Unknown)" instead.

<linux/acpi.h> will be changed to only include the header for
