From: Visuwesh <visuweshm <at> gmail.com> To: 57969 <at> debbugs.gnu.org Subject: bug#57969: 29.0.50; `device-class' errors when NAME is nil Date: Wed, 21 Sep 2022 13:15:19 +0530
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=
