This just removes few annoying warnings.
About the conversion of string to signed int.
- dev_index = boost::lexical_cast< unsigned int >( hackrf_serial );
+ dev_index = boost::lexical_cast< int >( hackrf_serial );
hackrf_device_list_open checks if value of dev_index is out
of range (eg negative) and returns proper error. In future negative value
can be used for something so this check is not necessary nor wanted.
