   4 Subject: Input: add a new EV_SW SW_RADIO event, for radio switches on laptops
   5
   6 Many laptops have rf-kill physical switches that are not keys, but slider
   7 or rocker switches.  Often (like in all ThinkPads with a radio kill slider
   8 switch), they have both a slider/rocker switch and a hot key.
   9
  10 Trying to kludge a real switch to act like a key is not a very smart thing
  11 to do if you can help it, and it gets specially bad when you are going to
  12 have both in the same machine.  So, we do the right thing and add an input
  13 EV_SW event for radio kill switches.
  14
  15 The EV_SW SW_RADIO event is defined with positive logic, i.e. when the
  16 switch is active, the radios are to be enabled.  When the switch is
  17 inactive, the radios are to be disabled.
