This device sometimes doesn't send touch release signals when moving from >=4 fingers to <4 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
MT_QUIRK_FORCE_MULTI_INPUT is not necessary for this device, but does no harm.

HID: multitouch: Add quirk for HONOR GLO-GXXX touchpad
[ Upstream commit 9ffccb691adb854e7b7f3ee57fbbda12ff70533f ]
Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch mode until the input mode feature is written by the host. The touchpad do report the input mode at touchpad(3), while itself working under mouse mode. As a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set feature in mt_set_input_mode for such device.
The touchpad reports as BLTP7853, which cannot retrive any useful manufacture information on the internel by this string at present. As the serial number of the laptop is GLO-G52, while DMI info reports the laptop serial number as GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.

HID: multitouch: Correct devm device reference for hidinput input_dev name
Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management.
Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.

Certain touchscreen devices, such as the ELAN9034, are oriented incorrectly and report touches on opposite points on the X and Y axes. For example, a 100x200 screen touched at (10,20) would report (90, 180) and vice versa.

The HID descriptor of this device contains two mouse collections, one for mouse emulation and the other for the trackpoint.
Both collections get merged and, because the first one defines X and Y, the movemenent events reported by the trackpoint collection are ignored.
Set the MT_CLS_WIN_8_FORCE_MULTI_INPUT class for this device to be able to receive its reports.
This fix is similar to/based on commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices").

HID: multitouch: new device class fix Lenovo X12 trackpad sticky
The trackpad of the given device sends continuous report of pointers status as per wxn8 spec. However, the spec did not clarify when the fingers are lifted so fast that between the interval of two report frames fingers on pad reduced from >=2 to 0. The second last report contains >=2 fingers with tip state 1 and the last report contains only 1 finger with tip state 0. Although this can happen unfrequently, a quick fix will be improve the consistency to 100%. A quick fix is to disable MT_QUIRK_ALWAYS_VALID and enable MT_QUIRK_NOT_SEEN_MEANS_UP.
Test for hid-tools is added in [1]
In addition to this, I2C device 04CA:00B1 may also need similar class but with MT_QUIRK_FORCE_MULTI_INPUT disabled (but it does not harm to enable it on non-multi-input device either). The respective owner has been notified and a patch may coming soon after test.

HID: multitouch: disable sticky fingers for UPERFECT Y
When a finger is on the screen, the UPERFECT Y portable touchscreen monitor reports a contact in the first place. However, after this initial report, contacts are not reported at the refresh rate of the screen as required by the Windows 8 specs.
This behaviour triggers the release_timer, removing the fingers even though they are still present.
To avoid it, add a new class, similar to MT_CLS_WIN_8 but without the MT_QUIRK_STICKY_FINGERS quirk for this device.

Palm ejection stops working on some Elan and Synaptics touchpad after commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices").
The commit changes the mt_class from MT_CLS_WIN_8 to MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied anymore.
So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is essentially MT_CLS_WIN_8.

HID: core: Sanitize event code and type when mapping input
When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap.
This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable".
Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses
Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.
