HID: Ignore battery for ELAN touchscreens 2F2C and 4116

2024-07-25T07:53:25Z

[ Upstream commit a3a5a37efba11b7cf1a86abe7bccfbcdb521764e ] At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected. The touchscreen reports a battery status of 0% and jumps to 1% when a stylus is used. The device ID was added and the battery ignore quirk was enabled for it.

HID: Add quirk for Logitech Casa touchpad

2024-06-27T11:52:14Z

[ Upstream commit dd2c345a94cfa3873cc20db87387ee509c345c1b ] 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: core: remove unnecessary WARN_ON() in implement()

2024-06-21T12:40:18Z

[ Upstream commit 4aa2dcfbad538adf7becd0034a3754e1bd01b2b5 ] Syzkaller hit a warning [1] in a call to implement() when trying to write a value into a field of smaller size in an output report. Since implement() already has a warn message printed out with the help of hid_warn() and value in question gets trimmed with: ... value &= m; ... WARN_ON may be considered superfluous. Remove it to suppress future syzkaller triggers.

HID: i2c-hid: elan: fix reset suspend current leakage

2024-06-16T11:51:05Z

commit 0eafc58f2194dbd01d4be40f99a697681171995b upstream. The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s shares the VCC33 supply with other peripherals that may remain powered during suspend (e.g. when enabled as wakeup sources). The reset line is also wired so that it can be left deasserted when the supply is off. This is important as it avoids holding the controller in reset for extended periods of time when it remains powered, which can lead to increased power consumption, and also avoids leaking current through the X13s reset circuitry during suspend (and after driver unbind). Use the new 'no-reset-on-power-off' devicetree property to determine when reset needs to be asserted on power down. Notably this also avoids wasting power on machine variants without a touchscreen for which the driver would otherwise exit probe with reset asserted.
