The braces of the unlikely() macro inside the if condition only cover the subtraction part, not the whole statement. This causes the result of the subtraction to be converted to zero or one. While that still works in this context, it causes static analysis tools to complain (and is just plain wrong). Fix the bracket placement and, while at it, simplify the if-condition. Also add a comment to the if-condition explaining what we expect the result to be and what happens on the failure path, as it seems to have caused a bit of confusion. This commit should not cause any difference in behavior or generated code. Reported-by:

Mostly based on Mark Pearson <markpearson@lenovo.com>'s thinkpad-acpi work but massaged to fit ideapad driver. Note that different from ThinkPads, IdeaPads's Thermal Hotkey won't trigger profile switch itself, we'll leave it for userspace programs. Tested on Lenovo Yoga-14S ARE Chinese Edition. Signed-off-by:

All recent ThinkPad BIOS-es support the GSKL method used to query the keyboard-layout used by the ECFW for the SHIFT + other-key key-press emulation for special keys such as e.g. the '=', '(' and ')' keys above the numpad on 15" models. So just checking for the method is not a good indicator of the model supporting getting/setting the keyboard_lang. On models where this is not supported GSKL succeeds, but it returns METHOD_ERR in the returned integer to indicate that this is not supported on this model. Add a check for METHOD_ERR and return -ENODEV if it is set to avoid registering a non-working keyboard_lang sysfs-attr on models where this is not supported.

After a rmmod thinkpad_acpi, lockdep pointed out this possible deadlock: Our _show and _store sysfs attr functions get called with the kn->active lock held for the sysfs attr and then take the profile_lock. sysfs_remove_group() also takes the kn->active lock for the sysfs attr, so if we call it with the profile_lock held, then we get an ABBA deadlock. platform_profile_remove() must only be called by drivers which have first *successfully* called platform_profile_register(). Anything else is a driver bug. So the check for cur_profile being set before calling sysfs_remove_group() is not necessary and it can be dropped. It is safe to call sysfs_remove_group() without holding the profile_lock since the attr-group group cannot be re-added until after we clear cur_profile. Change platform_profile_remove() to only hold the profile_lock while clearing the cur_profile, fixing the deadlock. Signed-off-by:

This patch is to create sysfs entry for setting keyboard language using ASL method. Some thinkpads models like T580 , T590 , T15 Gen 1 etc. has "=", "(',")" numeric keys, which are not displaying correctly, when keyboard language is other than "english". This patch fixes this issue by setting keyboard language to ECFW. Signed-off-by: -

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago.

Recently userspace has started making more use of SW_TABLET_MODE (when an input-dev reports this). Specifically recent GNOME3 versions will: 1. When SW_TABLET_MODE is reported and is reporting 0: 1.1 Disable accelerometer-based screen auto-rotation 1.2 Disable automatically showing the on-screen keyboard when a text-input field is focussed 2. When SW_TABLET_MODE is reported and is reporting 1: 2.1 Ignore input-events from the builtin keyboard and touchpad (this is for 360° hinges style 2-in-1s where the keyboard and touchpads are accessible on the back of the tablet when folded into tablet-mode) This means that claiming to support SW_TABLET_MODE when it does not actually work / reports correct values has bad side-effects. The check in the hp-wmi code which is used to decide if the input-dev should claim SW_TABLET_MODE support, only checks if the HPWMI_HARDWARE_QUERY is supported. It does *not* check if the hardware actually is capable of reporting SW_TABLET_MODE. This leads to the hp-wmi input-dev claiming SW_TABLET_MODE support, while in reality it will always report 0 as SW_TABLET_MODE value. This has been seen on a "HP ENVY x360 Convertible 15-cp0xxx" and this likely is the case on a whole lot of other HP models. This problem causes both auto-rotation and on-screen keyboard support to not work on affected x360 models. There is no easy fix for this, but since userspace expects SW_TABLET_MODE reporting to be reliable when advertised it is better to not claim/report SW_TABLET_MODE support at all, then to claim to support it while it does not work. To avoid the mentioned problems, add a new enable_tablet_mode_sw module-parameter which defaults to false. Note I've made this an int using the standard -1=auto, 0=off, 1=on triplett, with the hope that in the future we can come up with a better way to detect SW_TABLET_MODE support. ATM the default auto option just does the same as off.

The VBDL ACPI method enables button/switch reporting through the intel-vbtn device. In some cases the embedded-controller (EC) might call Notify() on the intel-vbtn device immediately after the the VBDL call to make sure that the OS is synced with the EC's button and switch state. If we register our notify_handler after evaluating VBDL this means that we might miss the Notify() calls made by the EC to sync the state. E.g. the HP Stream x360 Convertible PC 11 has a VGBS method which always returns 0, independent of the actual SW_TABLET_MODE state of the device; and immediately after the VBDL call it calls Notify(0xCD) or Notify(0xCC) to report the actual state. Move the evaluation of VBDL to after registering our notify_handler so that we don't miss any events. Cc: Elia Devito <eliadevito@gmail.com> Signed-off-by:

Some 2-in-1s have a broken VGBS method, so we cannot get an initial state for the switches from them. Reporting the wrong initial state for SW_TABLET_MODE causes serious problems (touchpad and/or keyboard events being ignored by userspace when reporting SW_TABLET_MODE=1), so on these devices we cannot register an input-dev for the switches at probe time. We can however register an input-dev for the switches as soon as we receive the first switches event, because then we will know the state. Note this mirrors the behavior of recent changs to the intel-hid driver which also registers a separate switches input-dev on receiving the first event on machines with a broken VGBS method.

Create 2 separate input-devs for buttons and switches, this is a preparation for dynamically registering the switches-input device for devices which are not on the switches allow-list, but do make Notify() calls with an event value from the switches sparse-keymap. This also brings the intel-vbtn driver inline with the intel-hid driver which is doing the same thing. Cc: Elia Devito <eliadevito@gmail.com> Signed-off-by:

Rework the wakeup path inside notify_handler() to special case the buttons (KE_KEY) case instead of the switches case. In case of a button wake event we want to skip reporting this, mirroring how the drivers/acpi/button.c code skips the reporting in the wakeup case (suspended flag set) too. The reason to skip reporting in this case is that some Linux desktop-environments will immediately resuspend if we report an evdev event for the power-button press on wakeup. Before this commit the skipping of the button-press was done in a round-about way: In case of a wakeup the regular sparse_keymap_report_event() would always be skipped by an early return, and then to avoid not reporting switch changes on wakeup there was a special KE_SW path with a duplicate sparse_keymap_report_event() call. This commit refactors the wakeup handling to explicitly skip the reporting for button wake events, while using the regular reporting path for non button (switches) wakeup events. No intentional functional impact. Cc: Elia Devito <eliadevito@gmail.com> Signed-off-by:
