On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an
internal data structure that holds platform config and is maintained by
the telemetry platform driver.

This is also applicable to the platforms where the BIOS supports IPC1
device under debug configurations but IPC1 is disabled by user or the
policy.

This change allows user to know the reason for not seeing entries under
/sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

A driver for LG Gram laptop supporting features not available through the
standard interfaces:

- Support for the 5 Fn keys that generate ACPI or WMI events.

- Two software controlled LEDs: keyboard backlight (also controlled by
  hardware) and touchpad LED.

- Extra features: reader mode, Fn lock, cooling mode, USB charge mode, and
  maximal battery charging level.

The original asus-wmi queues a work which calls the ACPI/WMI methods to
update the keyboard LED brightness.  Similar drivers - acer-wmi,
dell-wmi-led just call the ACPI/WMI methods directly without workqueues.

This patch simplifies the keyboard brightness updating process which
calls the kbd_led_update function directly without workqueue in
asus-wmi.

Clang warns that mlxplat_mlxcpld_msn201x_items is not going to be
emitted in the final assembly because it's only used in ARRAY_SIZE right
now, which is a compile time evaluation since the array's size is known.

drivers/platform/x86/mlx-platform.c:555:32: warning: variable
'mlxplat_mlxcpld_msn201x_items' is not needed and will not be emitted
[-Wunneeded-internal-declaration]

                               ^
1 warning generated.

It appears this was a copy and paste mistake from when this item was
first added. Use the definition in mlxplat_mlxcpld_msn201x_data so that
Clang no longer warns.

Some users have been reporting issues with thunderbolt being turned off
before fully initialized. This is suspected to be caused by userspace
turning off the Thunderbolt controller using intel-wmi-thunderbolt
prematurely.

Userspace has already made some mitigations for this situation:
https://github.com/hughsie/fwupd/commit/ef6f1d76983c9b66
https://github.com/hughsie/fwupd/commit/c07ce5b4889a5384

To allow easier debugging of this situation add output that can be turned
on with dynamic debugging to better root cause this problem.
