Pull x86 platform driver fix from Ilpo Järvinen: - Fix ACPI _DSM function index and bitmask usage for Dell DW5826e * tag 'platform-drivers-x86-v7.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: platform/x86: dell-dw5826e: fix ACPI _DSM function index and bitmask usage
PALC_DSM_FN_TRIGGER_PLDR was defined as BIT(1) (value 2).
acpi_evaluate_dsm() expects a 0-based function index integer (0, 1,
2, ...), whereas acpi_check_dsm() expects a bitmask of supported
function indices (BIT(1), BIT(2), ...).
Because PALC_DSM_FN_TRIGGER_PLDR was defined as BIT(1),
acpi_evaluate_dsm() was evaluating Function Index 2 instead of Function
Index 1, while acpi_check_dsm() was checking for Function Index 1
support.
Fix this by setting PALC_DSM_FN_TRIGGER_PLDR to 1 (the function index)
and passing BIT(PALC_DSM_FN_TRIGGER_PLDR) to acpi_check_dsm().

Pull x86 platform driver fixes from Ilpo Järvinen: - asus-wmi: Revert retaining battery charge threshold on boot due to userspace regression. Userspace assumed (errorneously) a non-zero return code from sysfs read implies feature is not supported but the correct way would be to check file visibility instead. This results in the kernel change breaking the functionality completely. Thus, we are taking timeout on the kernel side to allow userspace to sort their problem first. - intel/vsec: Free ACPI discovery data allocation on error paths * tag 'platform-drivers-x86-v7.2-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: platform/x86: asus-wmi: temporarily revert to setting a charge limit platform/x86/intel/vsec: free ACPI discovery data on early errors
A userspace regression has been observed leaving the battery charging
threshold unconfigured, so while the fix is being shipped revert
the change keeping the infrastructure in place to return to the
preferred behaviour as soon as it's appropriate to do.

intel_vsec_add_dev() may attach an ACPI discovery table copy to the
intel_vsec_device before passing ownership to intel_vsec_add_aux(). The
normal auxiliary-device release path frees that copy, but the earliest
intel_vsec_add_aux() failures free only the outer structure directly.
Route those direct frees through a common helper so acpi_disc is
released consistently on the parent, xarray, and ID allocation failure
paths.

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.

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.
