HID: Add input_register callback.
Add input_register callback which gets called after hid_configure_usage is called for all the reports and before the input device is registered. This allows individual drivers to do extra work like input mapping just before device registration. Based on discussions with David Herrmann <dh.herrmann@googlemail.com> Change-Id: Idab6fb4f7b1e5e569bd0410967288717e9d34c98 Signed-off-by: Jaikumar Ganesh <jaikumarg@android.com>
