haiku/headers/os/device/Joystick.h
Michael Lotz ef13dbda92 * Actually implement the relevant parts of BJoystick, i.e. reading the joystick
info and values. Inspired by and in parts based on the patch by caz_haiku in
  ticket #7429 (though rewritten completely due to the other changes). Thanks
  for the pointers!
* Clean up the mixup of internal joystick info and the one from
  joystick_driver.h so that BJoystick and the drivers talk about the same
  structures.
* Extensive coding style cleanup, simplifications, NULL checks, early returns,
  std::nothrow allocations, include sorting, argument naming, ... that kind of
  stuff.
* Added some TODO notes for remaining stuff.
* Automatic (and manual) whitespace cleanup.
