On gcc, enums are generally unsigned, except if a negative value
is declared. Due to that, warnings may happen there:

As other compilers might be using signed values, the better is to
keep the checks there, casting the value to avoid the warning.

Note: there is already a mantis_exit at the mantis driver. So,
this should be renamed to mantis_input_exit.

The mantis_input code is currently unused, as it doesn't implement the RC API
right.

Patches for it are sent for discussions, but were never
accepted. So, while this is not fixed, the entire code inside
mantis_input can simply be commented.
