Actually it's describing the main architecture of the driver, and wa put 
at this place due to the two lines just _above_ this comment:
/* joystick device poll interval in milliseconds */
#define MDPS_POLL_INTERVAL 50
A poll of 50 ms = 20Hz. And it's there to explain why I decided to use 
polling although in the documentation they say that interrupt can be 
generated whenever data is updated. (even if in general it's better to 
use interrupt driven than polling based)

Suggestions are welcome to make this comment more understandable :-)
