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]\fBregister\fR 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\&. .SH "NOTE" .PP the owner device is set up as parent of input device and users should not override it\&. .SH "COPYRIGHT" .br
