HID: uhid: add UHID_START and UHID_STOP events
We send UHID_START and UHID_STOP events to user-space when the HID core starts/stops the device. This notifies user-space about driver readiness and data-I/O can start now. This directly forwards the callbacks from hid-core to user-space. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
