NAME¶

devm_input_allocate_polled_device - allocate managed polled device

SYNOPSIS¶

ARGUMENTS¶

dev

DESCRIPTION¶

Returns prepared struct input_polled_dev or NULL. Managed polled input devices do not need to be explicitly unregistered or freed as it will be done automatically when owner device unbinds from * its driver (or binding fails). Once such managed polled device is allocated, it is ready to be set up and registered in the same fashion as regular polled input devices (using input_register_polled_device function). If you want to manually unregister and free such managed polled devices, it can be still done by calling input_unregister_polled_device and input_free_polled_device, although it is rarely needed.

NOTE¶

the owner device is set up as parent of input device and users should not override it.
