devm_input_allocate_device — allocate managed input device
struct input_dev * devm_input_allocate_device ( | struct device * dev) ; |
Returns prepared struct input_dev or NULL
.
Managed 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 managed input device is allocated,
it is ready to be set up and registered in the same fashion as regular
input device. There are no special devm_input_device_[un]register
variants, regular ones work with both managed and unmanaged devices,
should you need them. In most cases however, managed input device need
not be explicitly unregistered or freed.
