  Input: ambakmi - fix timeout handling in amba_kmi_write()
  Input: pxa930_trkball - fix write timeout handling
  Input: struct device - replace bus_id with dev_name(), dev_set_name()
  Input: bf54x-keys - fix debounce time validation
  Input: spitzkbd - mark probe function as __devinit
  Input: omap-keypad - mark probe function as __devinit
  Input: corgi_ts - mark probe function as __devinit
  Input: corgikbd - mark probe function as __devinit
  Input: uvc - the button on the camera is KEY_CAMERA
  Input: psmouse - make MOUSE_PS2_LIFEBOOK depend on X86
  Input: atkbd - make forced_release_keys[] static
  Input: usbtouchscreen - allow reporting calibrated data
