Pull input updates from Dmitry Torokhov: - a number of input drivers has been converted to use facilities provided by the device core to instantiate driver-specific attributes instead of using devm_device_add_group() and similar APIs - platform input devices have been converted to use remove() callback returning void - a fix for use-after-free when tearing down a Synaptics RMI device - a few flexible arrays in input structures have been annotated with __counted_by to help hardening efforts - handling of vddio supply in cyttsp5 driver - other miscellaneous fixups * tag 'input-for-v6.7-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (86 commits) Input: walkera0701 - use module_parport_driver macro to simplify the code Input: synaptics-rmi4 - fix use after free in rmi_unregister_function() dt-bindings: input: fsl,scu-key: Document wakeup-source Input: cyttsp5 - add handling for vddio regulator dt-bindings: input: cyttsp5: document vddio-supply Input: tegra-kbc - use device_get_match_data() Input: Annotate struct ff_device with __counted_by Input: axp20x-pek - avoid needless newline removal Input: mt - annotate struct input_mt with __counted_by Input: leds - annotate struct input_leds with __counted_by Input: evdev - annotate struct evdev_client with __counted_by Input: synaptics-rmi4 - replace deprecated strncpy Input: wm97xx-core - convert to platform remove callback returning void Input: wm831x-ts - convert to platform remove callback returning void Input: ti_am335x_tsc - convert to platform remove callback returning void Input: sun4i-ts - convert to platform remove callback returning void Input: stmpe-ts - convert to platform remove callback returning void Input: pcap_ts - convert to platform remove callback returning void Input: mc13783_ts - convert to platform remove callback returning void Input: mainstone-wm97xx - convert to platform remove callback returning void ...
