* @dev: input device associated with this keyboard
* @usbdev: usb device associated with this keyboard
* @old: data received in the past from the @irq URB representing which

* that are pressed, we are able to see key releases.
* @irq: URB for receiving a list of keys that are pressed when a
* new key is pressed or a key that was pressed is released.
* @led: URB for sending LEDs (e.g. numlock, ...)
* @newleds: data that will be sent with the @led URB representing which LEDs
* should be on
* @name: Name of the keyboard. @dev's name field points to this buffer
* @phys: Physical path of the keyboard. @dev's phys field points to this
* buffer
* @new: Buffer for the @irq URB
* @cr: Control request for @led URB
* @leds: Buffer for the @led URB
* @new_dma: DMA address for @irq URB
* @leds_dma: DMA address for @led URB
* @leds_lock: spinlock that protects @leds, @newleds, and @led_urb_submitted
* @led_urb_submitted: indicates whether @led is in progress, i.e. it has been
* submitted and its completion handler has not returned yet
* without resubmitting @led
