Therefore, each peripheral device is * implemented as an independent module and we probe on each device only the * modules for the hardware that really is available. * * Module registration is sequential. Unregistration is done in reverse order. * After device detection, the needed modules are loaded. Users can trigger * re-detection which causes all modules to be unloaded and then reload the * modules for the new detected device. * * wdata->input is a shared input device. It is always initialized prior to * module registration. If at least one registered module is marked as * WIIMOD_FLAG_INPUT, then the input device will get registered after all * modules were registered. * Please note that it is unregistered _before_ the "remove" callbacks are * called. This guarantees that no input interaction is done, anymore. However, * the wiimote core keeps a reference to the input device so it is freed only * after all modules were removed. It is safe to send events to unregistered * input devices. */ #include <linux/device.h> #include <linux/hid.h> #include <linux/input.h> #include <linux/spinlock.h> #include "hid-wiimote.h" /* * Keys * The initial Wii Remote provided a bunch of buttons that are reported as * part of the core protocol.
