Subject: [PATCH v2 5/5] Use LDJ_DEVICE macro for existing Logitech mice

Signed-off-by: Harry Cutts <hcutts@...omium.org>
---

Changes in v2:
* Changed the REL_WHEEL_HI_RES code to use micrometres (a.k.a. microns)
  as its units, instead of 256ths of a millimetre.
* Removed support for mice connecting over Bluetooth, due to a bug where
  the mouse's high-res mode and the driver's settings get out of sync
  when the mouse is power cycled.
* Moved the creation of the HID++ 1.0 function and the refactor to use
  the LDJ_DEVICE macro into separate patches.
* Added a couple of explanatory comments to the Logitech driver.
