bf9167a8b4 HID: intel-ish-hid: fix module device-id handling 
A late addititon to the intel-ish-hid framework caused a build failure
with clang, and introduced an ABI to the module loader that stops working
if any driver ever needs to bind to more than one UUID:

drivers/hid/intel-ish-hid/ishtp-fw-loader.c:1067:4: error: initializer element is not a compile-time constant

Change the ishtp_device_id to have correct documentation and a driver_data
field like all the other ones, and change the drivers to use the ID table
as the primary identification in a way that works with all compilers
and avoids duplciating the identifiers.

0b243c003e platform/x86: intel_skl_int3472: Correct null check 
The int3472-discrete driver can enter an error path after initialising
int3472->clock.ena_gpio, but before it has registered the clock. This will
cause a NULL pointer dereference, because clkdev_drop() is not null aware.
Instead of guarding the call to skl_int3472_unregister_clock() by checking
for .ena_gpio, check specifically for the presence of the clk_lookup, which
will guarantee clkdev_create() has already been called.

6cfce3ef80 platform/x86/intel: pmc/core: Add Alder Lake low power mode support for pmc core 
Alder Lake has 14 status registers that are memory mapped. These
registers show the status of the low power mode requirements. The
registers are latched on every C10 entry or exit and on every s0ix.y
entry/exit. Accessing these registers is useful for debugging any low
power related activities.

Thus, add debugfs entry to access low power mode status registers.

dcfbd31ef4 platform/x86: BIOS SAR driver for Intel M.2 Modem 
Dynamic BIOS SAR driver exposing dynamic SAR information from BIOS

The Dynamic SAR (Specific Absorption Rate) driver uses ACPI DSM
(Device Specific Method) to communicate with BIOS and retrieve
dynamic SAR information and change notifications. The driver uses
sysfs to expose this data to userspace via read and notify.

Sysfs interface is documented in detail under:
Documentation/ABI/testing/sysfs-driver-intc_sar

This function returns negative error codes, zero (to indicate that
everything has been completed successfully) and one (to indicate that
more resources need to be handled still).

This code prints an uninitialized error message when the function
returns one which potentially leads to an Oops.
