input_allocate_polled_device - allocate memory for polled device

The function allocates memory for a polled device and also for an input device associated with this polled device.

Definition at line 156 of file input-polldev.c.

void input_free_polled_device

)

input_free_polled_device - free memory allocated for polled device : device to free

The function frees memory allocated for polling device and drops reference to the associated input device.

input_register_polled_device - register polled device : device to register

The function registers previously initialized polled input device with input layer. The device should be allocated with call to input_allocate_polled_device(). Callers should also set up poll() method and set up capabilities (id, name, phys, bits) of the corresponding input_dev structure.

Definition at line 200 of file input-polldev.c.

void input_unregister_polled_device

(

struct input_polled_dev *

)

input_unregister_polled_device - unregister polled device : device to unregister

The function unregisters previously registered polled input device from input layer. Polling is stopped and device is ready to be freed with call to input_free_polled_device().
