/**
 * struct input_dev - represents an input device
 * @name: name of the device
 * @phys: physical path to the device in the system hierarchy
 * @uniq: unique identification code for the device (if device has it)
 * @id: id of the device (struct input_id)
 * @evbit: bitmap of types of events supported by the device (EV_KEY,
 *	EV_REL, etc.)
 * @keybit: bitmap of keys/buttons this device has
 * @relbit: bitmap of relative axes for the device
 * @absbit: bitmap of absolute axes for the device
 * @mscbit: bitmap of miscellaneous events supported by the device
 * @ledbit: bitmap of leds present on the device
 * @sndbit: bitmap of sound effects supported by the device
 * @ffbit: bitmap of force feedback effects supported by the device
 * @swbit: bitmap of switches present on the device
 * @keycodemax: size of keycode table
 * @keycodesize: size of elements in keycode table
 * @keycode: map of scancodes to keycodes for this device
 * @setkeycode: optional method to alter current keymap, used to implement
 *	sparse keymaps. If not supplied default mechanism will be used
 * @getkeycode: optional method to retrieve current keymap. If not supplied
 *	default mechanism will be used
 * @ff: force feedback structure associated with the device if device
 *	supports force feedback effects
 * @repeat_key: stores key code of the last key pressed; used to implement
 *	software autorepeat
 * @timer: timer for software autorepeat
 * @sync: set to 1 when there were no new events since last EV_SYNC
 * @abs: current values for reports from absolute axes
 * @rep: current values for autorepeat parameters (delay, rate)
 * @key: reflects current state of device's keys/buttons
 * @led: reflects current state of device's LEDs
 * @snd: reflects current state of sound effects
 * @sw: reflects current state of device's switches
 * @absmax: maximum values for events coming from absolute axes
 * @absmin: minimum values for events coming from absolute axes
 * @absfuzz: describes noisiness for axes
 * @absflat: size of the center flat position (used by joydev)
 * @open: this method is called when the very first user calls
 *	input_open_device(). The driver must prepare the device
 *	to start generating events (start polling thread,
 *	request an IRQ, submit URB, etc.)
 * @close: this method is called when the very last user calls
 *	input_close_device().
 * @flush: purges the device. Most commonly used to get rid of force
 *	feedback effects loaded into the device when disconnecting
 *	from it
 * @event: event handler for events sent _to_ the device, like EV_LED
 *	or EV_SND. The device is expected to carry out the requested
 *	action (turn on a LED, play sound, etc.) The call is protected
 *	by @event_lock and must not sleep
 * @grab: input handle that currently has the device grabbed (via
 *	EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
 *	recipient for all input events coming from the device
 * @event_lock: this spinlock is is taken when input core receives
 *	and processes a new event for the device (in input_event()).
 *	Code that accesses and/or modifies parameters of a device
 *	(such as keymap or absmin, absmax, absfuzz, etc.) after device
 *	has been registered with input core must take this lock.
 * @mutex: serializes calls to open(), close() and flush() methods
 * @users: stores number of users (input handlers) that opened this
 *	device. It is used by input_open_device() and input_close_device()
 *	to make sure that dev->open() is only called when the first
 *	user opens device and dev->close() is called when the very
 *	last user closes the device
 * @going_away: marks devices that are in a middle of unregistering and
 *	causes input_open_device*() fail with -ENODEV.
 * @dev: driver model's view of this device
 * @h_list: list of input handles associated with the device. When
 *	accessing the list dev->mutex must be held
 * @node: used to place the device onto input_dev_list
