Version 7 changes:
  - Changed name to hid-nintendo to fit modern naming conventions
  - Removed joycon_ctlr_destroy(), since it wasn't needed an could
    potentially invalidate a mutex while it could be in use on other
    threads
  - Implemented minor code improvements suggested by Silvan
  - The driver now waits to send subcommands until after receiving an
    input report. This significantly reduces dropped subcommands.
  - Reduced the number of error messages when disconnecting a
    controller.

Version 6 changes:
  - Improved subcommand sending reliabilty
  - Decreased rumble period to 50ms
  - Added rumble queue to avoid missing ff_effects if sent too quickly
  - Code cleanup and minor refactoring
  - Added default analog stick calibration

Version 5 changes:
  - Removed sysfs interface to control motor frequencies.
  - Improved rumble reliability by using subcommands to set it.
  - Changed mapping of the SL/SR triggers on the joy-cons to map to
    whichever triggers they lack (e.g. a left joycon's sl/sr map to
    TR and TR2). This allows userspace to distinguish between the
    normal and S triggers.
  - Minor refactors

Version 4 changes:
  - Added support for the Home button LED for the pro controller and
    right joy-con
  - Changed name from hid-switchcon to hid-joycon
  - Added rumble support
  - Removed ctlr->type and use hdev->product instead
  - Use POWER_SUPPLY_CAPACITY_LEVEL enum instead of manually translating
    to capacity percentages
  - Misc. minor refactors based on v3 feedback

Version 3 changes:
  - Added led_classdev support for the 4 player LEDs
  - Added power_supply support for the controller's battery
  - Made the controller number mutex static
  - Minor refactoring/style fixes based on Roderick's feedback from v2

Version 2 changes:
  - Switched to using a synchronous method for configuring the
        controller.
  - Removed any pairing/orientation logic in the driver. Every
    controller now corresponds to its own input device.
  - Store controller button data as a single u32.
  - Style corrections
