Input updates for v6.10-rc0

- a change to input core to trim amount of keys data in modalias string in case when a device declares too many keys and they do not fit in uevent buffer instead of reporting an error which results in uevent not being generated at all - support for Machenike G5 Pro Controller added to xpad driver - support for FocalTech FT5452 and FT8719 added to edt-ft5x06 - support for new SPMI vibrator added to pm8xxx-vibrator driver - missing locking added to cyapa touchpad driver - removal of unused fields in various driver structures - explicit initialization of i2c_device_id::driver_data to 0 dropped from input drivers - other assorted fixes and cleanups. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQST2eWILY88ieB2DOtAj56VGEWXnAUCZk/rJQAKCRBAj56VGEWX nOFVAQD8lfavuaJwEc0k/P39hZGOnTh423Um5gqIj8FOMw/V3AEA3D9IdTFC32DA JphZ5YvneDAfqu76ZRnjQi2oyOikygo= =8zDF -----END PGP SIGNATURE----- Merge tag 'input-for-v6.10-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input updates from Dmitry Torokhov: - a change to input core to trim amount of keys data in modalias string in case when a device declares too many keys and they do not fit in uevent buffer instead of reporting an error which results in uevent not being generated at all - support for Machenike G5 Pro Controller added to xpad driver - support for FocalTech FT5452 and FT8719 added to edt-ft5x06 - support for new SPMI vibrator added to pm8xxx-vibrator driver - missing locking added to cyapa touchpad driver - removal of unused fields in various driver structures - explicit initialization of i2c_device_id::driver_data to 0 dropped from input drivers - other assorted fixes and cleanups. * tag 'input-for-v6.10-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (24 commits) Input: edt-ft5x06 - add support for FocalTech FT5452 and FT8719 dt-bindings: input: touchscreen: edt-ft5x06: Document FT5452 and FT8719 support Input: xpad - add support for Machenike G5 Pro Controller Input: try trimming too long modalias strings Input: drop explicit initialization of struct i2c_device_id::driver_data to 0 Input: zet6223 - remove an unused field in struct zet6223_ts Input: chipone_icn8505 - remove an unused field in struct icn8505_data Input: cros_ec_keyb - remove an unused field in struct cros_ec_keyb Input: lpc32xx-keys - remove an unused field in struct lpc32xx_kscan_drv Input: matrix_keypad - remove an unused field in struct matrix_keypad Input: tca6416-keypad - remove unused struct tca6416_drv_data Input: tca6416-keypad - remove an unused field in struct tca6416_keypad_chip Input: da7280 - remove an unused field in struct da7280_haptic Input: ff-core - prefer struct_size over open coded arithmetic Input: cyapa - add missing input core locking to suspend/resume functions input: pm8xxx-vibrator: add new SPMI vibrator support dt-bindings: input: qcom,pm8xxx-vib: add new SPMI vibrator module input: pm8xxx-vibrator: refactor to support new SPMI vibrator Input: pm8xxx-vibrator - correct VIB_MAX_LEVELS calculation Input: sur40 - convert le16 to cpu before use ...
