Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote). Upstream: https://github.com/xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2)

/**
|
|
* struct input_polled_dev - simple polled input device
|
|
* @private: private driver data.
|
|
* @open: driver-supplied method that prepares device for polling
|
|
* (enabled the device and maybe flushes device state).
|
|
* @close: driver-supplied method that is called when device is no
|
|
* longer being polled. Used to put device into low power mode.
|
|
* @poll: driver-supplied method that polls the device and posts
|
|
* input events (mandatory).
|
|
* @poll_interval: specifies how often the poll() method should be called.
|
|
* Defaults to 500 msec unless overridden when registering the device.
|
|
* @poll_interval_max: specifies upper bound for the poll interval.
|
|
* Defaults to the initial value of @poll_interval.
|
|
* @poll_interval_min: specifies lower bound for the poll interval.
|
|
* Defaults to 0.
|
|
* @input: input device structure associated with the polled device.
|
|
* Must be properly initialized by the driver (id, name, phys, bits).
|
|
*
|
|
* Polled input device provides a skeleton for supporting simple input
|
|
* devices that do not raise interrupts but have to be periodically
|
|
* scanned or polled to detect changes in their state.
