Since the component_state->input[i] is only valid when it is active, the content of input[i] is undefined if it is inactive. The user must check the state->active_inputs with input index firstly before using state->input[i]. Refine the function to_d71_input_id and directly move such check into it. Simplify the using and avoid problem that caller forget the valid check.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
