[PATCH 2/3] HID: picolcd: explicitly claim hid devices with HID_CLAIMED_OTHER

[David Herrmann <dh.herrmann@googlemail.com>]

Instead of using an ugly workaround to make hid_hw_start() correctly
initialize the device, we now explicitely set HID_CLAIMED_OTHER before
initializing the hid device. This tells the hid-core to accept the device
even if no generic hid driver gets loaded.
