HID: asus: Only set EV_REP if we are adding a mapping
Make asus_input_mapping() only set EV_REP if we are adding a mapping. The T100CHI bluetooth keyboard dock has a few input reports for which we do not create any mappings (these input-reports are present in the descriptors but never send). The hid-asus code relies on the HID core not creating input devices for input-reports without any mappings. But the present of the EV_REP but counts as a mapping causing 6 /dev/input/event# nodes to be created for the T100CHI bluetooth keyboard dock. This change brings the amount of created /dev/input/event# nodes / input-devices down to 4. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
