Merge the fixes branch into the for-next branch to resolve Makefile
conflict and include the power supply accessor work that is required
by the upcoming Uniwill driver.

Registering the "other mode" notifier fails if that is disabled:
x86_64-linux-ld: drivers/platform/x86/lenovo/wmi-gamezone.o: in function `lwmi_gz_probe':
wmi-gamezone.c:(.text+0x336): undefined reference to `devm_lwmi_om_register_notifier'
This could be fixed by adding a stub helper, but a Kconfig 'select'
seems simpler here.

[ij: retained the other selects as wmi-gamezone is using them directly.]

Adds lenovo-wmi-other driver which provides the Lenovo "Other Mode" WMI
interface that comes on some Lenovo "Gaming Series" hardware. Provides a
firmware-attributes class which enables the use of tunable knobs for SPL,
SPPT, and FPPT.

attribute is supported by the hardware, as well as its default_value,
max_value, min_value, and step increment.

Adds lenovo-wmi-events driver. The events driver is designed as a
general entrypoint for all Lenovo WMI Events. It acts as a notification
chain head that will process event data and pass it on to registered
drivers so they can react to the events.
Currently only the Gamezone interface Thermal Mode Event GUID is
implemented in this driver. It is documented in the Gamezone
documentation.

Merge fixes back into for-next to be able to take dell_rbu change that
is build on top of fixes material, and to bring lenovo related changes
in sync after the move under lenovo/ subdir in the for-next branch and
diverging changes in the fixes branch.

devm_pinctrl_register_mappings()
Use devm_pinctrl_register_mappings(), so the core automatically unregisters
the pinctrl mappings. It makes the code easier to read.

When KCOV is enabled all functions get instrumented, unless the
__no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions[1], we have
to handle differences in how GCC's inline optimizations get resolved.
For thinkpad_acpi routines, this means forcing two functions to be
inline with __always_inline.

Some Ideapad models support a battery conservation mode which limits the
battery charge threshold for longer battery longevity. This is currently
exposed via a custom conservation_mode attribute in sysfs.
The newly introduced charge_types sysfs attribute is a standardized
replacement for laptops with a fixed end charge threshold. Setting it to
`Long Life` would enable battery conservation mode. The standardized
user space API would allow applications such as UPower to detect laptops
which support this battery longevity mode and set it.
Tested on an Lenovo ideapad U330p.
