Commit 5829f8a897 ("platform/x86: ideapad-laptop: Send
KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send
KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set
and the touchpad-state has not been changed by the EC itself already.
This was done under the assumption that this would be good to do to make
the touchpad-toggle hotkey work on newer models where the EC does not
toggle the touchpad on/off itself (because it is not routed through
the PS/2 controller, but uses I2C).
But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC
triggers an ACPI notify with VPC event bit 5 set on resume, which would
now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop
environment responds by disabling the touchpad in software, breaking
the touchpad (until manually re-enabled) on resume.
It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves
things on new models and at least some new models like the Yoga 7-15ITL5
don't have a touchpad on/off toggle hotkey at all, while still sending
ACPI notify events with VPC event bit 5 set.
So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when
receiving an ACPI notify events with VPC event bit 5 and the touchpad
state as reported by the EC has not changed.
Note this is not a full revert the code to cache the last EC touchpad
state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events
on resume.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Remove the ACPI-HID + DMI-id deny-lists for touchpad_ctrl_via_ec and
instead make it a module option which defaults to false.
The touchpad sysfs attribute allowing directly writing VPCCMD_W_TOUCHPAD
from userspace has been leading to a lot of bug-reports / patches adding
both ACPI HID + dmi-id based deny-lists for it which then need to be
expanded all the time going forward leading to a high maintenance load.
At the same time the touchpad sysfs attribute is not a standard Linux
userspace API. So it is not used in standard desktop-enviroments, instead
it is only used in the following 2 rare circumstances:
1. Ideapad specific control-panel like applets
2. Custom scripts written by users
For 1. these applets need to already deal with the touchpad sysfs attr
sometimes not being there because of the existing deny lists so hiding
it be default should not cause an issue; and most desktop environments
already have a touchpad-disable option in their native control-panel,
so having an ideapad specific toggle for this is not necessary.
For 2. since these users are already customizing their systems they
can add the module option if they want to keep using the touchpad
sysfs attribute.

Commit d69cd7eea9 ("platform/x86: ideapad-laptop: Disable touchpad_switch
for ELAN0634") from Janary 2021 added a flag hiding the touchpad sysfs-attr
and disabling ideapad_sync_touchpad_state() because some devices
"do not use EC to switch touchpad".
At the same time this added a write(VPCCMD_W_TOUCHPAD, 1) call at probe
time on these same devices. This seems to be copied from the rfkill code
which does something similar when hw rfkill support is disabled.
But for the rfkill code this is known to be necessary on some models,
where as for the touchpad control no motivation is given for doing this
and prior to this patch there were no reports of needing to do this.
So this seems unnecessary; and it is best to avoid poking the hardware
unnecessary to avoid unwanted side effects, so remove this.

On recent Ideapad models the EC does not control the touchpad at all,
so instead of sending KEY_TOUCHPAD_ON/ _OFF on touchpad toggle hotkey
events, ideapad-laptop should send KEY_TOUCHPAD_TOGGLE and let userspace
handle the toggling.
Check for this by checking if the value read from VPCCMD_R_TOUCHPAD
actually changes when receiving a touchpad-toggle hotkey event; and
if it does not change send KEY_TOUCHPAD_TOGGLE to userspace to let
userspace enable/disable the touchpad in software.
Note this also drops the priv->features.touchpad_ctrl_via_ec check from
ideapad_sync_touchpad_state() so that KEY_TOUCHPAD_TOGGLE will be send
on laptops where this is not set too. This can be safely dropped now
because the i8042_command(I8042_CMD_AUX_ENABLE/_DISABLE) call is now
guarded by its own feature flag.

Recently there have been multiple patches to disable the ideapad-laptop's
touchpad control code, because it is causing issues on various laptops:
Commit d69cd7eea9 ("platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634")
Commit a231224a60 ("platform/x86: ideapad-laptop: Disable touchpad_switch")
The turning on/off of the ps2 aux port was added specifically for
the IdeaPad Z570, where the EC does toggle the touchpad on/off LED and
toggles the value returned by reading VPCCMD_R_TOUCHPAD, but it does not
actually turn on/off the touchpad.
The ideapad-laptop code really should not be messing with the i8042
controller on all devices just for this special case.
Add a new ctrl_ps2_aux_port flag set based on a DMI based allow-list
for devices which need this workaround, populating it with just
the Ideapad Z570 for now.
This also adds a module parameter so that this behavior can easily
be enabled on other models which may need it.

Commit 3ae86d2d47 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock

to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam
interrupts until the laptop is rebooted.
Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to

The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION()
macro and the ACPI handle produced by the former comes from the
ACPI device object produced by the latter, so it is way more

VPC event bit 10 gets set on a Yoga 300-11IBR when the EC believes that the
device has changed between laptop/tent/stand/tablet mode.
The EC relies on getting angle info from 2 accelerometers through a special
windows service calling a DSM on the DUAL250E ACPI-device. Linux does not
do this, making the laptop/tent/stand/tablet mode info unreliable.
Ignore VPC event bit 10 to avoid the warnings triggered by the default case
in ideapad_acpi_notify().
Note that the plan for Linux is to have iio-sensor-proxy read the 2
accelerometers and have it provide info about which mode 360° hinges

Consumers can differentiate an error from a successful read much more
easily if the read() call fails with an appropriate errno instead of
returning a magic string like "-1". This introduces an ABI change, but
not many users are expected to be relying on the previous behavior,
and this change makes this module conforming to the standard behavior
that sysfs attribute show/store callbacks return an appropriate
errno in case of failure. Thus the ABI breakage is deemed justified.
