2023-10-04HID: lenovo: Detect quirk-free fw on cptkbd and stop applying workaroundMikhail Khvainitski
Built-in firmware of cptkbd handles scrolling by itself (when middle button is pressed) but with issues: it does not support horizontal and hi-res scrolling and upon middle button release it sends middle button click even if there was a scrolling event. Commit 3cb5ff0220e3 ("HID: lenovo: Hide middle-button press until release") workarounds last issue but it's impossible to workaround scrolling-related issues without firmware modification. Likely, Dennis Schneider has reverse engineered the firmware and provided an instruction on how to patch it [1]. However, aforementioned workaround prevents userspace (libinput) from knowing exact moment when middle button has been pressed down and performing "On-Button scrolling". This commit detects correctly-behaving patched firmware if cursor movement events has been received during middle button being pressed and stops applying workaround for this device.

2023-09-29HID: prodikeys: Replace deprecated strncpy() with strscpy()Justin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

2023-08-24HID: multitouch: Correct devm device reference for hidinput input_dev nameRahul Rameshbabu
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.

2023-08-22HID: logitech-dj: Fix error handling in logi_dj_recv_switch_to_dj_mode()Nikita Zhandarovich
Presently, if a call to logi_dj_recv_send_report() fails, we do not learn about the error until after sending short HID_OUTPUT_REPORT with hid_hw_raw_request(). To handle this somewhat unlikely issue, return on error in logi_dj_recv_send_report() (minding ugly sleep workaround) and take into account the result of hid_hw_raw_request().

2023-08-21HID: i2c-hid: elan: Add ili9882t timingCong Yang
The ili9882t is a TDDI IC (Touch with Display Driver). The datasheet specifies there should be 60ms between touch SDA sleep and panel RESX. Doug's series[1] allows panels and touchscreens to power on/off together, so we can add the 65 ms delay in i2c_hid_core_suspend before panel_unprepare. Because ili9882t touchscrgeen is a panel follower, and needs to use vccio-supply instead of vcc33-supply, so set it NULL to ili9882t_chip_data, then not use vcc33 regulator.
