On some Dell XPS models WMI events of type 0x0000 reporting a keycode of
0xe00c get reported when the brightness of the LCD panel changes.
This leads to us reporting false-positive kbd_led change events to
userspace which in turn leads to the kbd backlight OSD showing when it
should not.
We already read the current keyboard backlight brightness value when
reporting events because the led_classdev_notify_brightness_hw_changed
API requires this. Compare this value to the last known value and filter
out duplicate events, fixing this.
Note the fixed issue is esp. a problem on XPS models with an ambient light
sensor and automatic brightness adjustments turned on, this causes the kbd
backlight OSD to show all the time there.

Though ChromeOs uses the exported API as part of their S0ix failsafe

We can revisit this when ChromeOs kernel team is able to get their S0ix

Drivers should not 'select' a subsystem. Instead they should depend
on it. If the subsystem is disabled, the user probably did that for
a purpose and one driver shouldn't be changing that.
This also makes all platform/x86/ drivers consistent w.r.t depending on
INPUT instead of selecting it.

Calling acpi_wmi_init() at the subsys_initcall() level causes ordering
issues to appear on some systems and they are difficult to reproduce,
because there is no guaranteed ordering between subsys_initcall()
calls, so they may occur in different orders on different systems.
In particular, commit 86d9f48534e8 (mm/slab: fix kmemcg cache
creation delayed issue) exposed one of these issues where genl_init()
and acpi_wmi_init() are both called at the same initcall level, but
the former must run before the latter so as to avoid a NULL pointer
dereference.
For this reason, move the acpi_wmi_init() invocation to the
initcall_sync level which should still be early enough for things
to work correctly in the WMI land.

Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.
Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

The new notify_handler logic determining if autorelease should be used or
not is a bit awkward, and can result in more than one call to
sparse_keymap_report_event for the same event (scancode). The nesting
and long lines also made it difficult to read.
Simplify the logic by eliminating a level of nesting with a goto and
always calculate autorelease and val so we can make a single call to
sparse_keymap_report_event.

Suspend with shallow wakes is not a useful parameter since the phenomena
does not exist on deployed devices and is only a parameter of use during
device power-on phase. The field always reads zero. Additionally there
are other easier methods to detect it, e.g., if the S0ix counter
increments by more than one during suspend. Hence the field is superfluous
and can be removed.
This patch also slightly renames the S0ix total field for better
viewability.

Suspend stats are not reported consistently due to a limitation in the PMC
firmware. This limitation causes a delay in updating the s0ix counters and
residencies in the telemetry log upon s0ix exit. As a consequence, reading
these counters from the suspend-exit notifier may result in zero read.
This patch fixes this issue by cross-verifying the s0ix residencies from
the GCR TELEM registers in case the counters are not incremented in the
telemetry log after suspend.
