According to the docstring of `device-class', nil is a valid value for
the NAME argument however it errors out since `x-device-class' uses
`downcase' without checking if NAME is non-nil.  Backtrace is below,

Debugger entered--Lisp error: (wrong-type-argument char-or-string-p nil)
  downcase(nil)
  (let ((downcased-name (downcase name))) (cond ((string-match-p "XTEST" name) 'test) ((string= "Virtual core pointer" name) 'core-pointer) ((string= "Virtual core keyboard" name) 'core-keyboard) ((string-match-p "eraser" downcased-name) 'eraser) ((string-match-p " pad" downcased-name) 'pad) ((or (or (string-match-p "wacom" downcased-name) (string-match-p "pen" downcased-name)) (string-match-p "stylus" downcased-name)) 'pen) ((or (string-prefix-p "xwayland-touch:" name) (string-match-p "touchscreen" downcased-name)) 'touchscreen) ((or (string-match-p "trackpoint" downcased-name) (string-match-p "stick" downcased-name)) 'trackpoint) ((or (string-match-p "mouse" downcased-name) (string-match-p "optical" downcased-name) (string-match-p "pointer" downcased-name)) 'mouse) ((string-match-p "cursor" downcased-name) 'puck) ((or (string-match-p "keyboard" downcased-name) (string= name "USB USB Keykoard")) 'keyboard) ((string-match-p "button" downcased-name) 'power-button) ((string-match-p "touchpad" downcased-name) 'touchpad) ((or (string-match-p "midi" downcased-name) (string-match-p "piano" downcased-name)) 'piano) ((or (string-match-p "wskbd" downcased-name) (and (string-match-p "/dev" downcased-name) (string-match-p "kbd" downcased-name))) 'keyboard)))
