DEVM_INPUT_ALLOCATE_(9)                  Input Subsystem                  DEVM_INPUT_ALLOCATE_(9)



NAME
       devm_input_allocate_polled_device - allocate managed polled device

SYNOPSIS
       struct input_polled_dev * devm_input_allocate_polled_device(struct device * dev);

ARGUMENTS
       dev
           device owning the polled device being created

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.
