7ba618e893 platform/x86: thinkpad_acpi: Add support for new phone link hotkey 
The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s
Gen 5 laptops includes a symbol showing a smartphone and a laptop
chained together.  According to the user manual, it starts the Microsoft
Phone Link software used to connect to Android/iOS devices and relay
messages/calls or sync data.

These laptops send the 0x1320 hkey event when the key is pressed.  Map
this event to the new KEY_LINK_PHONE keycode.

cec8c359f8 Input: i8042 - Add support for platform filter contexts 
Currently the platform filter cannot access any driver-specific state
which forces drivers installing a i8042 filter to have at least some
kind of global pointer for their filter.

Allow callers of i8042_install_filter() to submit a context pointer
which is then passed to the i8042 filter. This frees drivers from the
responsibility of having to manage this global pointer themself.

Also introduce a separate type for the i8042 filter (i8042_filter_t)
so that the function definitions can stay compact.

Tested on a Dell Inspiron 3505.

1e4e3dff9e platform/x86: dell-smo8800: Add support for probing for the accelerometer i2c address 
Unfortunately the SMOxxxx ACPI device does not contain the i2c-address
of the accelerometer. So a DMI product-name to address mapping table
is used.

Add support to have the kernel probe for the i2c-address for models
which are not on the list.

The new probing code sits behind a new probe_i2c_addr module parameter,
which is disabled by default because probing might be dangerous.

1d334211aa platform/x86: alienware-wmi: Improve hdmi_mux, amplifier and deepslp group creation 
Devices with hdmi_mux, amplifier or deepslp quirks create a sysfs group
for each available feature. To accomplish this, helper create/remove
functions were called on module init, but they had the following
problems:

 - Create helpers called remove helpers on failure, which in turn tried
   to remove the sysfs group that failed to be created
 - If group creation failed mid way, previous successfully created groups
   were not cleaned up
 - Module exit only removed hdmi_mux group

To improve this, drop all helpers and let the platform driver manage these
sysfs groups, while controlling visibility with their respective quirks.

d03cfde56f platform/x86: firmware_attributes_class: Simplify API 
The module core already guarantees that a module can only be unloaded
after all other modules using its symbols have been unloaded.
As it's already the responsibility of the drivers using
firmware_attributes_class to clean up their devices before unloading,
the lifetime of the firmware_attributes_class can be bound to the
lifetime of the module.
This enables the direct usage of firmware_attributes_class from the
drivers, without having to go through the lifecycle functions,
leading to simplifications for both the subsystem and its users.

cc0809b752 platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from i2c-i801 to dell-lis3lv02d 
Various Dell laptops have an lis3lv02d freefall/accelerometer sensor.
The lis3lv02d chip has an interrupt line as well as an I2C connection to
the system's main SMBus.

The lis3lv02d is described in the ACPI tables by an SMO88xx ACPI device,
but the SMO88xx ACPI fwnodes are incomplete and only list an IRQ resource.

So far this has been worked around with some SMO88xx specific quirk code
in the generic i2c-i801 driver, but it is not necessary to handle the Dell
specific instantiation of i2c_client-s for SMO88xx ACPI devices there.

The kernel already instantiates platform_device-s for these with an
acpi:SMO88xx modalias. The drivers/platform/x86/dell/dell-smo8800.c
driver binds to this platform device but this only deals with
the interrupt resource. Add a drivers/platform/x86/dell/dell-lis3lv02d.c
which will matches on the same acpi:SMO88xx modaliases and move
the i2c_client instantiation from the generic i2c-i801 driver there.

Moving the i2c_client instantiation has the following advantages:

1. This moves the SMO88xx ACPI device quirk handling away from the generic
i2c-i801 module which is loaded on all Intel x86 machines to a module
which will only be loaded when there is an ACPI SMO88xx device.

2. This removes the duplication of the SMO88xx ACPI Hardware ID (HID) table
between the i2c-i801 and dell-smo8800 drivers.

3. This allows extending the quirk handling by adding new code and related
module parameters to the dell-lis3lv02d driver, without needing to modify
the i2c-i801 code.

  315 |                 snprintf(name, sizeof(name), "domain%d", i);

Inspecting the code tells that maximum i in intel_plr_probe() will fit
into u8 because it comes from:

struct intel_tpmi_pfs_entry {

        u64 num_entries:8;

...but compiler does not know that. Saving one byte in name[] at the
expense of a warning with W=1 seems a bad trade so simply make it
name[17].
