Hans de Goede c158c2afc9 HID: lenovo: Add support for Thinkpad X1 Tablet Thin keyboard
The Thinkpad X1 Tablet Thin keyboard's HID interface for the media-keys
and other special functions, is quite similar to the Thinkpad 10 ultrabook
keyboard's mouse/media-keys HID interface.

The only difference is that it needs a bit different key mappings.

Add support for the mute-LED and the non-standard media-keys on this
keyboard by re-using the tp10_ultrabook_kbd code combined with a new
lenovo_input_mapping_x1_tab_kbd() function.

Hans de Goede 2d0f1c071a HID: lenovo: Rework how the tp10ubkbd code decides which USB interface to use
Instead of looking for a hdev with a type of HID_TYPE_USBMOUSE find
the interface for the mute/mic-mute/fn-lock LEDs by checking for the
output-report which is used to set them.

This is a preparation patch for adding support for the LEDs on the
X1 tablet thin keyboard which uses the same output-report, but has
a separate (third) USB interface for the touchpad/mouse functionality.

Hans de Goede e2da5ff435 HID: lenovo: Set default_triggers for the mute and micmute LEDs
The mute and mic-mute LEDs should be automatically turned on/off based
on the audio-card's mixer settings.

Add the standardized default-trigger names for this, so that the alsa
code can turn the LEDs on/off as appropriate (on supported audio cards).

This brings the mute/mic-mute LED support inline with the thinkpad_acpi
support for the same LEDs in keyboards directly connected to the
laptop's embedded-controller.

Hans de Goede 617103246c HID: lenovo: Map mic-mute button to KEY_F20 instead of KEY_MICMUTE
Mapping the mic-mute button to KEY_MICMUTE is technically correct but
KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X,
which does not fit in 8 bits, so it does not work.

Because of this userspace is expecting KEY_F20 instead,
theoretically KEY_MICMUTE should work under Wayland but even
there it does not work, because the desktop-environment is
listening only for KEY_F20 and not for KEY_MICMUTE.

Hans de Goede 033c978680 HID: lenovo: Remove lenovo_led_brightness_get()
The led_classdev already contains a cached value of the last set
brightness, the brightness_get callback is only meant for LED drivers
which can read back the actual / current brightness from the hardware.

Since lenovo_led_brightness_get() just returns the last set value
it does not add any functionality, so we can just remove it.

Hans de Goede 34348a8661 HID: lenovo: Check hid_get_drvdata() returns non NULL in lenovo_event()
The HID lenovo probe function only attaches drvdata to one of the
USB interfaces, but lenovo_event() will get called for all USB interfaces
to which hid-lenovo is bound.

This allows a malicious device to fake being a device handled by
hid-lenovo, which generates events for which lenovo_event() has
special handling (and thus dereferences hid_get_drvdata()) on another
interface triggering a NULL pointer exception.

Add a check for hid_get_drvdata() returning NULL, avoiding this
possible NULL pointer exception.

Hans de Goede 658d04e6eb HID: lenovo: Fix lenovo_led_set_tp10ubkbd() error handling
Fix the following issues with lenovo_led_set_tp10ubkbd() error handling:

1. On success hid_hw_raw_request() returns the number of bytes sent.
   So we should check for (ret != 3) rather then for (ret != 0).

2. Actually propagate errors to the caller.

3. Since the LEDs are part of an USB keyboard-dock the mute LEDs can go
   away at any time. Don't log an error when ret == -ENODEV and set the
   LED_HW_PLUGGABLE flag to avoid errors getting logged when the USB gets
   disconnected.

Hans de Goede 4942942838 HID: lenovo: Fix spurious F23 key press report during resume from suspend
The Ultrabook Keyboard sends a spurious F23 key-press when resuming
from suspend. GNOME uses F23 to toggle the touchpad on/off so this causes
the OSD graphics for the touchpad toggle to show on resume.

The keyboard does not actually have a F23 key, se we can simple fix it
by marking the 0x00070072 HID usage, which normally is F23, to be ignored.

Jamie Lentin 94eefa2713 HID: lenovo: Use native middle-button mode for compact keyboards
By default the middle button is in a compatibility mode, and generates
standard wheel events when dragging with the middle trackpoint button.
Unfortunately this is buggy:
* The middle button comes up before starting wheel events, causing a middle
  click on whatever the mouse cursor was sitting on
* The USB keyboard always generates the "native" horizontal wheel event,
  regardless of mode.

Instead, enable the "native" mode the Windows driver uses, and add support
for the custom events this generates. This fixes the USB keyboard wheel
events, and the middle-click up event comes after the wheel events.
