rtapi_app_main - User-provided function to initialize a component

       None

       The  body  of  rtapi_app_main, which is provided by the component author, generally consists of a call to
       rtapi_init or hal_init, followed by other component-specific initialization code.

       rtapi_app_main - User-provided function to initialize a component

       Called automatically by the rtapi infrastructure in an initialization (not realtime) context.

       Return 0 for success.  Return a negative errno value  (e.g.,  -EINVAL)  on  error.   Existing  code  also
       returns RTAPI or HAL error values, but using negative errno values gives better diagnostics from insmod.
