    HID: trivial devm conversion for special hid drivers · abf832bf
    Benjamin Tissoires authored
    It is safe to use devres allocation within the hid subsystem:
    - the devres release is called _after_ the call to .remove(), meaning
      that no freed pointers will exists while removing the device
    - if a .probe() fails, devres releases all the allocated ressources
      before going to the next driver: there will not be ghost ressources
      attached to a hid device if several drivers are probed.
    
    Given that, we can clean up a little some of the HID drivers. These ones
    are trivial:
    - there is only one kzalloc in the driver
    - the .remove() callback contains only one kfree on top of hid_hw_stop()
    - the error path in the probe is easy enough to be manually checked
